D3 Geomap Integration

Looking at the options of the adding a map to the topology. Today it looks like you only support the AlbersUSA map. Documentation seems also to state it requires D3 libs. 

Would there be an easy to get the global geo map from D3 as background in the topology services instead of the USA only map. 

How could you put this into NextUI as if the license would even allow to do so.

d3.geomap - Create Geographic Maps for the Web

 Would be great if they just included is out of the box in NextUI too.  like the style of the artzub one even more: http://d3.artzub.com/wbca/

 Actually  NeXt support global geo map. Because of performance issue, I removed those from documentation but code is still there. Source code : next/WorldMapLayout.js at master · opendaylight/next · GitHub 

And an example : World Map - JSFiddle  

You need to do is register a WorldMap layout when topo is ready. and then use 'WorldMap' layout. You need to put the json file to you server. 

topo.registerLayout('WorldMap', new nx.graphic.Topology.WorldMapLayout()) 

layoutType: 'WorldMap',

layoutConfig: {

     longitude: 'model.longitude',

     latitude: 'model.latitude',

     worldTopoJson: '//bl.ocks.org/mbostock/raw/4090846/world-50m.json'

} 

P.S. The performance of Global map is quite bad, so i have two different approach.

1. I use Canvas/WebGL to rendering the map. Zooming performance is quit good, but not fully developed yet. Once I finished, i will commit that to code repo.

2. Use leafletjs as an background. Not deep dive into this, if you are interested, we could work on this together.
