As a fun data visualisation experiment – and as a way to practice my new found interest in Node.js – I decided to plot on a map of the world all the people who contributed to the recent release of WordPress 3.6. The map can be seen further down, but first a brief description of how I went about it.
I decided to generate a GeoJSON file of the contributor’s locations so it can be displayed wherever and however the open GeoJSON format is supported, not least on GitHub which recently added support for automatic rendering of GeoJSON files.
