SVG

Went to an interesting session hosted by a developer from Mexico who's using Perl and SVG to generate animated/dynamic renderings of patient medical data and reports. The process replaces the existing cruddy manual process they were using to spit out aggregated patient data in a series of graphs.

They started by creating a sample graph (imagine something plotting heart-rate or blood pressure or something over time) in Adobe Illustrator, then exported that with sample plotted points to an SVG file (which Illustrator can do)

He then wraps the SVG in XSLT placing for-each statements in the place of the sample data plots that will iteratate over real patient data fed into a XSLT engine with the SVG/XSL file. The XSLT can also then be used to render different graph styles or data types or ranges bt passing params to it. Very cool.

Also demod some impressive SVG based interactive web apps that you'd swear were Flash if you didnt know better. They use Javascript to make the interactive magic happen, and seems like they would probably take a lot of work a there arent really any useful (and certainly no open-source) development GUI's

There was some talk about SVG viewers and the like, it appears that we're basically stuck with the Adobe SVG plug-in at the moment, and a few dedicated SVG players like the Apache group Squiggle player that ships with their Batik Java based SVG toolkit.
