leaflet-d3-layer

utilizes Mike Bostock's excellent instructions to use D3 to render GeoJSON features on a Leaflet Map

logic is wrapped into an object that extends Leaflet's own GeoJSON layer, so its easy to add to a map using Leaflet's usual pattern:

var d3Layer = new L.GeoJSON.d3({...insert geojson here...});
var map = new L.Map("map").addLayer(d3Layer);

L.GeoJSON.d3.async allows you to create a layer that references a geojson data service, such as a WFS provided by Geoserver.

var asyncD3Layer = new L.GeoJSON.d3.async("http:/url/for/geoserver/wfs");
var map = new L.Map("map").addLayer(asyncD3Layer)

example application

still working...

• there is definitely a better way to handle adding / removing data from the map using (D3's update patterns)[http://bl.ocks.org/mbostock/3808218]
• is this a good way to handle unique-value symbology?
• probably "async" layer should be branded and focused for what it is: a connector to a Geoserver WFS, although it would work right now for any GeoJSON data service that accepts a bbox query paramter
