Graphy graphthings.

Two things, both graph-related:

NEWSDAQLOG

A pretty visualization for a stupid little trading game, plotting the graphs using Ruby and Gruff: NEWSDAQ graphs (Git repository)

Quota

A mashup of google trends and yahoo finance - compare stock values with search volumes: Quota (Git repository). This one uses SVG::TT::Graph for plotting, and is interesting insofar as that I’ve managed to make that module produce really pretty graphs via some stylesheet fumbling.

Also, one can just include those stock/trend graphs in places now by just constructing the right image URL. The parameters are explained on the Quota demo page.
