Pictures say more than a thousand words. This is true for your data as well. With Google Chart you can now easily generate charts of your data. No expertise required. Just make sure you format your data correctly, add it to the Google Chart URL, and it will return a nice graph.

It was very simple to create the following graph:

.. with the following URL:

http://chart.apis.google.com/chart?cht=pc
&chtt=Percentage+of+Chart+Which+Resembles+Pac-man
&chco=FDFF00|49005F
&chs=500x200
&chd=t:78,22
&chl=Resembling+Pac-man|Not+resembling+Pac-man
&chp=0.628

I'm not about to write full documentation on how-to do this, because Google already did that. Besides, I have better things to do like using their API to show nice benchmarking graphs.

Enjoy!
