chart_pie
Show a pie chart.
This is an utility tag providing a simplified interface to the pie chart feature of the {% google_chart %} tag. It has an easier way to define the data.
Example of simple pie chart:
{% chart_pie data=[["firefox",23],
["internet explorer", 67],
["safari",4],
["chrome",3],
["other", 3]]
%}
This generates the following image tag:
<img class='google_chart' alt='google chart'
src='http://chart.apis.google.com/chart?&cht=p&chts=909090,10&chs=300x150&chg=0,0,1,5&chf=bg,s,ffffff|c,s,ffffff&chdlp=b&chbh=-3,3,7&chxt=x&chxl=0:|firefox|internet%20explorer|safari|chrome|other&chxs=0,909090,10&chco=&chds=0,100&chd=t:23,67,4,3,3&chls=1,1,0' width='300' height='150' />
