This is a web app that displays an interactive 'slippy' map of South African election results. It uses a slightly modified version of TileStache to serve vector geography tiles (representing municipalities, wards, etc.); see this commit for the necessary modification. The front-end uses Leaflet plus Glenn Robertson's GeoJSON Tile Layer to display the map.
Live version and data
A live version of the app with results from the 2009 and 2014 elections can be seen at http://elections.adrianfrith.com/. The PostgreSQL databases containing the data can be downloaded from the following links: 2014, 2009. Those are 700MB files each, but if you just want the underlying data you can download:
