 Torque lets you render big, timeseries or categorical data in the client. This is useful for many modern applications that need more than just a static map. Early versions of Torque have been used to visualize human movement, Twitter activity, biodiversity data, and many more large-scale datasets.

-# Torque API
-
-
-## L.TorqueLayer(options)
-
-One of two core classes for the Torque library - it is used to create an animated torque layer with custom settings.
-
-### Usage example
-
-```js
-  // initialize a torque layer that uses the CartoDB account details and SQL API to pull in data
-  var torqueLayer = new L.TorqueLayer({
-    user       : 'viz2',
-    table      : 'ow',
-    cartocss:  CARTOCSS
-  });
-```
-
-### Options
-
-##### Provider options
-
-| Option    | type       | Default   | Description                            |
-|-----------|:-----------|:----------|:---------------------------------------|
-| provider  | string     | ```sql_api```   | Where is the data coming from |
-
-##### CartoDB data options (SQL API provider)
-
-| Option    | type       | Default   | Description                            |
-|-----------|:-----------|:----------|:---------------------------------------|
-| user      | string     | ```null```      | CartoDB account name. Found as, accountname.cartodb.com|
-| table     | string     | ```null```      | CartoDB table name where data is found  |
-| sql       | string     | ```null```      | SQL query to be performed to fetch the data. You must use this param or table, not at the same time |
-
-
-### Time methods
-
-| Method    | options    | returns   | Description                            |
-|-----------|:-----------|:----------|:---------------------------------------|
-| ```setStep(step)``` | ```time numeric```    | ```this```   | sets the animation to the step indicated by ```step```, must be between 0 and ```steps```|
-| ```play()```| | ```this```| starts the animation
-| ```stop()```| | ```this```| stops the animation and set time to step 0
-| ```pause()```| | ```this```| stops the animation but keep the current time (play enables the animation again)
-| ```toggle()```| | ```this```| toggles (pause/play) the animation 
-| ```getStep()``` | | current animation step (integer)   | gets the current animation step
-| ```getTime()``` | | current animation time (Date) | gets the real animation time
-
-
-
-### Style methods 
-
-| Method    | options    | returns   | Description                            |
-|-----------|:-----------|:----------|:---------------------------------------|
-| ```setCartoCSS(cartocss)``` | ```cartocss string```    | ```this```   | style the map rendering using client-side cartocss | 
-
-The full CartoCSS spec is not supported by Torque but instead only a limited subset with some additions related to torque rendering. To see the full list of supported parameters, read the [Torque CartoCSS documentation here](CartoCSS.md). ``value`` and ``zoom`` variables can be used. ``value`` is the value of aggregation (see ``countby`` constructor option). ``zoom`` is the current zoom being rendered
-
-TorqueLayer currently expects ```marker``` styling
-
-##### CartoCSS Example
-
-This should be ```string``` encoded in Javascript
-
-```css
-#layer {,
-  marker-fill: #662506;
-  marker-width: 20;
-  [value > 1] { marker-fill: #FEE391; }
-  [value > 2] { marker-fill: #FEC44F; }
-  [value > 3] { marker-fill: #FE9929; }
-  [value > 4] { marker-fill: #EC7014; }
-  [value > 5] { marker-fill: #CC4C02; }
-  [value > 6] { marker-fill: #993404; }
-  [value > 7] { marker-fill: #662506; }
-  [frame-offset = 1] {  marker-width: 20; marker-fill-opacity: 0.05;}', // renders the previos frame
-  [frame-offset = 2] {  marker-fill: red; marker-width: 30; marker-fill-opacity: 0.02;}', // renders two frames ago from the current being rendered
-}
-```
-
-### Interaction methods (only available for Leaflet)
-| Method    | options    | returns   | Description                            |
-|-----------|:-----------|:----------|:---------------------------------------|
-| ```getValueForPos(x, y[, step])```| | an object like { bbox:[], value: VALUE } if there is value for the pos, null otherwise | allows to get the value for the coordinate (in map reference system) for a concrete step. If step is not specified the animation one is used. This method is expensive in terms of CPU so be careful. It returns the value from the raster data not the rendered data |
-| ```getActivePointsBBox(step)```|  | list of bbox | returns the list of bounding boxes active for ``step``
-| ```invalidate()```|  | | forces a reload of the layer data.
-
-
-# Google Maps Layers
-
-## GMapsTorqueLayer(options) 
-This class does exactly the same than ``L.TorqueLayer`` but using Google Maps. The main difference is that this class
-is not a layer is a overlay so in order to add it to the map use ``layer.setMap`` instead of ``overlayMapTypes``. See [Overlay view](https://developers.google.com/maps/documentation/javascript/reference#OverlayView) reference in Google Maps API doc. 
-
-### Options
-
-##### options
-| Option    | type       | Default   | Description                            |
-|-----------|:-----------|:----------|:---------------------------------------|
-| map | google.maps.Map |    | google.maps.Map instance |
-
-see ``L.TorqueLayer`` for the rest of the options.

+## Getting Started
+
+Although the most straightforward way to use Torque is through either CARTO Builder, or by passing the layer's viz.json to [CARTO.js]({{site.cartojs_docs}}/), many use cases work best with the standalone Torque.js. Assuming you have a public dataset with a `date` column, it is really simple to create an animated map with the library. First, you need to have a Leaflet map prepared in an HTML page:
+
+```html
+  <link rel="stylesheet" href="http://cdn.leafletjs.com/leaflet/v0.7.7/leaflet.css" />
+  <body>
+    <div id="map"></div>
+    <script src="http://cdn.leafletjs.com/leaflet/v0.7.7/leaflet.js"></script>
+    <script>
+      var map = new L.Map('map', {
+        zoomControl: true,
+        center: [40, 0],
+        zoom: 3
+      });
+
+      L.tileLayer('http://{s}.api.cartocdn.com/base-dark/{z}/{x}/{y}.png', {
+        attribution: 'CARTO'
+      }).addTo(map);
+    </script>
+  </body>
+```
+
+This HTML file automatically generates the Torque.js library, which includes any Torque dependencies. For Torque to work with your table, you only need a username, the name of the table, and a [CartoCSS]({{site.styling_cartocss}}/) string to style the map. Leaflet's method `addTo` adds the Torque layer to the map. `play` runs the animation with the options specified in the CartoCSS properties.
+
+```html
+  <script>
+    var CARTOCSS = [
+      'Map {',
+      '-torque-time-attribute: "date";',
+      '-torque-aggregation-function: "count(cartodb_id)";',
+      '-torque-frame-count: 760;',
+      '-torque-animation-duration: 15;',
+      '-torque-resolution: 2',
+      '}',
+      '#layer {',
+      '  marker-width: 3;',
+      '  marker-fill-opacity: 0.8;',
+      '  marker-fill: #FEE391; ',
+      '  comp-op: "lighten";',
+      '}'
+    ].join('\n');
+
+    var torqueLayer = new L.TorqueLayer({
+      user       : 'your_username',
+      table      : 'your_table_name',
+      cartocss: CARTOCSS
+    });
+    torqueLayer.addTo(map);
+    torqueLayer.play()
+  </script>
+```
+
+You can use any kind of tile source outside CARTO, by specifying the location of a [valid TileJSON](https://github.com/mapbox/tilejson-spec) file:
+
+```javascript
+  var torqueLayer = new L.TorqueLayer({
+    tileJSON: 'http://url.to/tile.json'
+    cartocss: CARTOCSS
+  });
+```
+
+Optionally, it is also possible to use a custom SQL query for your visualization:
+
+```javascript
+  var torqueLayer = new L.TorqueLayer({
+    user       : 'your_username',
+    table      : 'your_table_name',
+    sql_query  : 'SELECT * FROM your_table_name WHERE whatever'
+    cartocss: CARTOCSS
+  });
+```
+
+Like in a video player, you can use animation control methods such as `play`, `stop` and `pause` at any point. Torque's animator fires a `change:time` event each time the animation "ticks" to the next frame, and there are a number of properties and methods that can be run during playback, which are detailed in the [API reference]({{site.torque_docs}}/reference/). At any point, for example, the styling of the layer's markers can be changed using the `layer.setCartoCSS('##style##')`.
+
+### Usage Examples
+The best way to start learning about the library is by taking a look at the [examples section]({{site.torque_docs}}/examples/).

+
+`-torque-clear-color`
+Color used to clear canvas on each frame.
+
+`-torque-frame-count`
+Number of animation steps/frames used in the animation. If the data contains a fewer number of total frames, the lesser value will be used.
+
+`-torque-resolution`
+Spatial resolution in pixels. A resolution of 1 means no spatial aggregation of the data. Any other resolution of N results in spatial aggregation into cells of NxN pixels. The value N must be power of 2.
+
+`-torque-animation-duration`
+Animation duration in seconds.
+
+`-torque-aggregation-function`
+A function used to calculate a value from the aggregate data for each cell. See [-torque-resolution](#-torque-resolution).
+
+`-torque-time-attribute`
+The table column that contains the time information used create the animation.
+
+`-torque-data-aggregation`
+A linear animation will discard previous values while a cumulative animation will accumulate them until it restarts.

+## Advanced Torque.js Interaction Methods
+
+### Torque Layers
+
+While you can add multiple layers with Torque.js, this is not recommended as it effects performance.
+
+#### Torque Layer Source Object (_type: 'torque'_)
+
+This layer source object is used for Torque maps. Note that it does not allow sublayers.
+
+##### Example
+
+```javascript
+{
+  type: 'torque', // Required
+  order: 1, // Optional
+  options: {
+    query: "SQL statement",   // Required if table_name is not given
+    table_name: "table_name",   // Required if query is not given
+    user_name: "your_user_name", // Required
+    cartocss: "CartoCSS styles" // Required
+  }
+}
+```
+
+
+### Interaction Methods for a Torque Layer
+
+Used to create an animated torque layer with customized settings.
+
+```javascript
+// initialize a torque layer that uses the CARTO account details and SQL API to pull in data
+var torqueLayer = new L.TorqueLayer({
+  user : 'viz2',
+  table : 'ow',
+  cartocss: CARTOCSS
+});
+```
+
+#### getValueForPos(_x, y[, step]_)
+
+##### Arguments
+
+Name | Description
+--- | --- 
+`getValueForPos(_x, y[, step]_)` |  Allows to get the value for the coordinate (in map reference system) for a concrete step. If a step is not specified, the animation step is used. Use caution, as this method increases CPU usage
+
+##### Returns
+
+An object, such as a { bbox:[], value: VALUE } if there is value for the pos, otherwise, it is null. 
+ It returns the value from the raster data, not the rendered data.
+
+#### getValueForBBox(_xstart, ystart, xend, yend_)
+
+##### Arguments
+
+Name | Description
+--- | --- 
+`getValueForBBox(_xstart, ystart, xend, yend_)` |  An accumulated numerical value from all the torque areas, within the specified bounds
+
+##### Returns
+
+Returns a number.
+
+#### getActivePointsBBox(_step_)
+
+##### Arguments
+
+Name | Description
+--- | --- 
+`getActivePointsBBox(_step_)` |  The list of bounding boxes active for `step`
+
+##### Returns
+
+Returns a list of values.
+
+#### invalidate()
+
+##### Arguments
+
+Name | Description
+--- | --- 
+`invalidate()` | Forces a reload of the layer data
+
+**Tip:** All of these interaction methods are available for Google Map layers, with the exception of `invalidate`.
+
+##### Example of Interaction Methods for a Torque Layer

+## Torque Time Slider
+
+You can use the `time_slider` option to show an animated time slider with Torque layers. This option is enabled by default when creating visualizations with [cartodb.createVis]({{site.cartojs_docs}}/v3/reference/#cartodbcreatevis) and [createLayer]({{site.cartojs_docs}}/v3/reference/#cartodbcreatelayermap-layersource--options--callback). Both require a map_id DOM object.
+
+**Enable / Disable the Torque Time Slider**
+
+Description | The Torque time slider is enabled by default, for your visualization or layer.
+Sample Torque.js Code | `{ time_slider: true });`
+Default Value | `true`, enabled by default.
+Available Values | See [boolean]({{site.styling_cartocss}}/#boolean).
+Related Examples | To disable the time slider option, use `time_slider: false`. See [No Torque Time Slider - Example Code](http://bl.ocks.org/michellechandra/081ca7160a8c782266d2).<br/><br/>For a code example about how to use the `time_slider` option to modify a Torque map, see [Torque with a Custom Time Slider](http://bl.ocks.org/csobier/cebdd47242d7ca98ec5e).
+
+**Note:** The `time_slider` option is specific for Torque.js only. All the other CARTO.js options are also supported for Torque.js. For the complete list of arguments, options, and returns, see [CARTO.js API Methods]({{site.cartojs_docs}}/v3/reference/#api-methods).
+
+
+### Customize Animation for your Time Slider
+
+You can customize the animation of your Torque time slider by editing the `-torque-frame-count` and `-torque-animation-duration` CartoCSS properties. (Optionally, you can create a [CARTO.js]({{site.cartojs_docs}}/v3/reference/#api-methods) map to create a custom time slider). This section also describes how time interval data is aggregated, and describes the formula used to calculate time buckets.
+
+- [`-torque-frame-count`]({{site.styling_cartocss}}/#-torque-frame-count-number) specifies the number of animation steps/frames in your torque animation. You can change the time slider timestamp by adjusting the number of steps.<br /><br />**Tip:** In CARTO Builder, this is the STEPS value when the style is ANIMATED.
+
+- [`-torque-animation-duration`]({{site.styling_cartocss}}/#-torque-animation-duration-number) specifies the length of time for your animation, in seconds. You can adjust the duration of the animation as needed.<br /><br />**Tip:** In CARTO Builder, this is the DURATION value when the style is ANIMATED.
+
+#### Aggregating Time Interval Data
+
+Before customizing the time slider, you should understand how Torque time interval data is calculated. Torque aggregates time (rather than use an exact start time and end from your column fields). Torque calculates the time interval as follows:
+
+- Reads the first date/time stamp from your dataset
+- Reads the last date/time stamp to from your dataset
+- Aggregates the time period based on the first and last date/time stamp (including seconds)
+- Once the time interval is defined, it breaks the time period up in smaller "buckets"
+- The number of buckets is based on the number of [Steps]({{site.styling_cartocss}}/#-torque-frame-count-number) you select for your Torque map
+- Each bucket, or step, is one animation frame
+  
+Thus, the start and end time for each bucket depends on the number of divided steps (not a specific start time or end time that you entered). 
+
+**Note:** If you are creating Torque maps with CARTO Builder, the date format of the Torque time slider is automatically calculated by CARTO and cannot be edited. See [Calculating the Time Slider in CARTO Builder](#calculating-the-time-slider-in-carto-builder) for more details.
+
+#### Formula for Calculating Time Buckets
+
+The following formula can help you calculate the number of steps for your Torque data.
+
+`time = times.start + (times.end - times.start)*(step/total_steps);`
+
+Where:
+
+- `time` = time at each hop
+- `times.start` = the earliest time in your date/time column
+- `times.end` = the latest time in your date/time column
+
+The Torque time slider displays these buckets of time, animating the entire sequence of your dataset, and divides the time according to the number of specified steps. You can alter the [duration]({{site.styling_cartocss}}/#-torque-animation-duration-number) of the animation, and adjust the time slider timestamp with the number of [Steps]({{site.styling_cartocss}}/#-torque-frame-count-number).
+
+##### Calculating the Time Slider in CARTO Builder
+
+When creating Torque maps with CARTO Builder, the date format of the Torque time slider is automatically calculated by CARTO, depending on the range of time in your dataset. It cannot be edited. If your data contains the following range of time, the time slider displays as described:
+
+- Time range is _less than one day_, the time slider displays the _time_
+- Time range is _less than three days_, the time slider displays the _day and time_
+- Time range is _more than three days, but less than a year_, the time slider displays the _month/day/year_
+- Time range is _more than a year_, the time slider displays the _month/year_

+## How spatial aggregation works
+
+When the Torque library renders points, it does not render exactly the same points you have in the database; instead it aggregates the points in clusters in order to speed up rendering and data transfer.
+
+So imagine you have this CartoCSS:
+
+```css
+Map {
+  -torque-aggregation-function:"count(cartodb_id)";
+  -torque-resolution: 2;
+}
+```
+
+This means that for the current zoom level, Torque will fetch points in clusters of 2x2 pixels. Every cluster has a value calculated by the function defined after ``-torque-aggregation-function``. In the case above, the value will be the number of points inside that cluster. That value can be accessed from CartoCSS using the variable `value`.
+
+Every cluster is renderer as a point.
+
+Given that you can do:
+
+```css
+#layer {
+[value > 1] { marker-fill: #000; }
+[value > 4] { marker-fill: #400; }
+[value > 16] { marker-fill: #800; }
+[value > 32] { marker-fill: #F00; }
+}
+```
+
+This would render the point with different colors depending on the number of points inside it.
+
+## Can I use strings with Torque?
+
+In general you can **not** do:
+```css
+[column = 'mytext'] { marker-fill: red; }
+```
+
+There are two reasons for this limitation:
+  - cluster does not contain values for all the columns, you can only use ``value`` variable
+  - you would need to use an aggregation function for strings
+
+So how could I use strings column with Torque?
+
+Imagine you have a string column (`team`) with two values, "team A" and "team B", and you want to color "team A" points to be red and "team B" to be blue, you could add a new column on the fly:
+
+```javascript
+torqueLayer.setSQL("select *, (CASE WHEN team='team A' THEN 1 ELSE 2 END) as team_n from table");
+```
+
+and then apply this CartoCSS:
+
+```css
+Map {
+  ...
+  -torque-aggregation-function: "round(avg(team_n))";
+  ...
+}
+
+#layer {
+  ...
+  marker-fill: #FF0000;
+  // avg of 1 and 2
+  [value > 1.5] { marker-fill: #0000FF; }
+  ...
+}
+```      
+
+**Tip:** CartoCSS is one the tools of the CARTO platform. You can learn more about the different [components of CARTO platform]({{site.fundamental_docs}}/components/), or directly dig into [CartoCSS]({{site.styling_cartocss}}/) details.
