[Chicago-talk] financial charting

[Jay Strauss]

Thanks Sean,

I looked at Flot
(and amcharts, highcharts, raphael, open flash charts2, dyngraphs...) and
starting to get a bit confused.

I like the google stuff because all the software sits on their servers, and
you just pass the data.

On the other hand, the other packages like flot have more options (i think)
