A colleague just reminded me of this blog: Information Aesthetics
which has a great collection of visualization sites, tools, and applications.

Their most recent post is about Trulia, a real estate search engine, who has a couple of interesting tools allowing one to overlay real estate data on maps. I also love their use of sparklines to illustrate activity on the site.

In a different forum, I mentioned VisualComplexity, another great site for inspiration. They have a lot of network visualization examples, including a number of science specific ones.

Which blogs are you reading? Which sites are inspiring to you? Have any favorite posts / examples to share?
