Client Side Heatmap

Author: Alastair Aitchison

Category: Layout

Module Size: 9kb (minified 2.5kb)

Original Source: Bing Maps AJAX v7 Heatmap Library

Dependencies: Client browser must support the <canvas> element (IE7+/Chrome/FF3.6+)


This module allows you to easily create "heatmap" overlays to visually analyse the distribution of a set of point data. Heatmap layers can be customised by changing the intensity and radius of the heatspot created around each datapoint, together with custom colour gradients including alpha transparency.

Hi, is there a similar library for the Bing Maps Silverlight control as well ?
