Show a pie chart with 3D effect.

This scomp is just a convenient interface to the [\\{% chart_pie
%\\}](/id/doc_template_scomp_scomp_chart_pie#scomp-chart-pie) scomp with the `threed` argument set to true.

For example:


```django
{% chart_pie3d data=[[\"firefox\",23],
                     [\"internet explorer\", 67],
                     [\"safari\",4],
                     [\"chrome\",3],
                     [\"other\", 3]]
%}
```

Gives:


```django
<img class='google_chart' alt='google chart' src='http://chart.apis.google.com/chart?&cht=p3&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'/>
```
