Animated Wind Map without 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.
This version here is not using SSVG, and renders up to 8X slower than the version with SSVG. You can see the version with SSVG here. 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.
