Visualization for Offline Purposes
Libraries and Credits
I made use of matplotlib toolkits’s Basemap for the background world map. This was really nice to use, with a whole bunch of projections available for plotting the map. I also found a great library called [py_geo_voronoi] (https://github.com/Softbass/py_geo_voronoi) that aids plotting Voronoi diagrams on map-sized plots. Utilizing one of this library’s functions, I obtained the
Polygon objects corresponding to each of the polygon in the Voronoi diagram. Then, I processed these polygons to get coordinates corresponding to the world map I had prepared. Polygon by polygon, I plotted them on the map.
What’s in the Code?
The code for bringing this data on a world map and constructing Voronoi polygons is surprisingly small with the easy to use libraries! The full code along with the included libraries can be found here. Download the directory and run:
$ python2 server_locations.py < geolist_locations
Here is how the Voronoi diagram on a Basemap looks:
