Improved map geometry by removing axes and implementing a MapView class. The MapView includes, currently as a beta feature, client side projection. Part of the improved geometry is the new series.data.geometry option to make it easier working with GeoJSON.
UPGRADE NOTESEXPANDCOLLAPSE
Programmatically zooming the map by running Axis.setExtremes() no longer works. Instead, use MapView.setView.
