Graphy is looking for a new maintainer.

Update: Considering Google Wave is now effectively dead, the authors would be surprised to see any interest in this project. Wave was cool, while it lasted, and having collaborative graph editing was even cooler. This page will remain up for historical purposes, despite providing no practical value.

Graphy extends Google Wave with the ability to collaborate on flow charts and graphs. Graphy searches for a marker (#!dot) at the top of a blip, and when found, adds a gadget to the bottom of the blip which presents an image of the graph. Graph edges are expressed with simple statements like

a -> b

Graphy is currently hosted on Google AppEngine at graph-wave@appspot.com .

Graphy is implemented as a robot and gadget combo. The robot watches blips for edits and uses a third-party server to generate images in SVG format. The gadget is responsible for displaying the graph and switching between views.

Graphy was originally developed by Elliott Slaughter, Brian Lee, Sean Chan, and Jonathan Ku at Intuit Inc.

TODO:

• Update to the Wave API v2. Supposedly most of the problems we encountered in the original implementation have been fixed now.
• The gadget sometimes shows an xml parse error rather than the graph. Refreshing one or more times seems to fix it. I suspect it has to do with timing issues between servers....
• Find an alternative to webdot? (Right now, running Graphy requires a third-party server in order to run webdot.)
