CanvasLayer – A Google Maps API utility library

A library for adding a <canvas> layer to a Google Maps JavaScript API v3 map and a small API for efficiently using it to visualize data using the 2d canvas API or WebGL. Analytics

Reference documentation

Live Examples

Two simple examples are provided, demonstrating methods to integrate CanvasLayer with the 2d canvas API and WebGL, respectively.

CanvasLayer exposes the raw <canvas> DOM element directly, however, so it can be used with any library that renders to a <canvas> element. See the examples for two possible ways of keeping the rendered content and the underlying map in sync.
