I have packaged a simple version of my treemap algorithm, along with example usage, CSS, and images for those who are interested. I really had a lot of fun with this. I used in on an aggregator site called roomformilk, and elsewhere. I’m also using it as a backend admin tool on a site of mine to see what users are using how much bandwidth.
You can download the package here. (ZIP file)
I’m still experimenting with it. I took the roomformilk code, and juryrigged it to take in my GMail RSS feed for which I am subscribed to FlashCoders. It’s pretty cool to get a searchable index of Flash-related questions and answers with a treemap navigation interface.
I’d LOVE to get my hands on the Figleaf database for Flashcoders and build a real searchable archive out of it. It would take a bit of work though, since there’d be an issue with tainting the index with mispelled words and ASCII art. There’s way too much ASCII art in there. ; )
