Yahoo! Pipes and the HTML5 canvas tag

Google Code Blog: Yahoo! Pipes and the HTML5 canvas tag: "Yahoo! Pipes is a free online service that lets you remix popular feed types (json, xml, rss, and atom) and create data mashups using a visual editor. You can use Pipes to run your own web projects, or publish and share your own web service without ever having to write a line of code. Pipes also allows you to create feeds from web sites that don't provide RSS/XML by extracting data straight from the HTML document. In this post, we'll talk about how the Pipes editor uses the HTML5 canvas tag extensively, challenges we faced using the canvas tag and a few solutions we came up with to address said challenges."
