Animated Wind Map with SSVG
This example shows the ease of creating complicated visualizations with SVG, and having them rendered smoothly as multi-process canvas applications using Scalable Scalable Vector Graphics.
You can see the version without SSVG here (warning: slow). The only difference is inclusion of this script tag:
<script src="https://intervis-projects.ccs.neu.edu/ssvg/ssvg-auto.js"></script>
All design credit goes to by Martin Viégas and Martin Wattenberg, as the design is heavily inspired by their Wind Map.
The technique to animate a fading path in SVG is more succinctly shown on this block.
