data visualization

[jangkoo]

Hey friends,

I am looking for some methods to create charts that read data from database,
something similar to this site : http://cm.asu.edu/ (http://cm.asu.edu/#)

I found some source here :
http://sixrevisions.com/javascript/20-fresh-javascript-data-visualization-libraries/ but I feel that is complicated. I just need to plot chart for once, and some how take data from database or xml file.
any recommendations for me?

Thanks in advance for helping.
