A Node-RED node to provide world
map web page for plotting "things" on.
+### Changes
+ - v1.0.0 - now uses socket.io to connect to backend - means this node now has an input connection
+ (like "proper" nodes should :-), and you no longer need a websocket node in parallel.
+ Obviously this is a breaking change hence the major version number bump. Also thus adds a `worldmap in`
+ node to handle events coming from the map interaction. (to be documented more fully but are fairly obvious).
+
### Install
Run the following command in your Node-RED user directory - typically `~/.node-red`

Plots "things" on a map. The map will be served from `{httpRoot}/worldmap`
-To use this node you must also place a **websocket out** node onto the workspace
-and set the endpoint to
-
- {httpRoot}/ws/worldmap
-
The minimum **msg.payload** must contain `name`, `lat` and `lon` properties, e.g.
{name:"Joe", lat:51, lon:-1.05}
