GeoJSON Plugin

Note: this plugin is experimental

New in Mapnik 2.1

This plugin can read GeoJSON. Previously GeoJSON reading in Mapnik was only supported through the OGR Plugin. But Mapnik 2.1 now internally has support for in-memory RtREE indexes and a robust JSON parser - so why not provide an extremely fast native GeoJSON plugin?

For more details on the motivations and design of this plugin see: https://github.com/mapnik/mapnik/issues/1413
