An interactive multi-line chart.

Note, I borrowed a bit of code from Duopixel's excellent code sample here.

Getting Started

I recently made my first map with MapBox's new WebGL+JavaScript API. There aren't many examples of how to do this yet, even on MapBox's API page, so I'll document my own experience here.

The Van Gogh Map

My map is made of several textures taken from Van Gogh paintings. The long-term goal is to allow a user to select which artworks they want to take textures from, but for now there is just one setting.

Why are we changing maps?

        self.reader = codecs.getreader(encoding)(f)

EPSG: 4326 uses a coordinate system on the surface of a sphere or ellipsoid of reference.
WGS 84 - Earth as Geoid. -Mercator

EPSG: 3857 uses a coordinate system PROJECTED from the surface of the 
sphere. Earth as perfectly sphere. -Web Mercator

Think of it as this way:

EPSG 4326 uses a coordinate system the same as a GLOBE (curved surface). 
EPSG 3857 uses a coordinate system the same as a MAP (flat surface).
