<p>jqPlot bakes up the best pie and donut charts you've ever tasted!  Like bar and filled line plots, pie and donut slices highlight when you mouse over.</p>

<div id="chart1" style="height:300px; width:500px;"></div>

<pre class="code prettyprint brush: js"></pre>

<p>Too many calories in that pie?  Get all the taste without the filling!  Highlighting and data labels are still supported.  You can even cut out the slices!</p>

<div id="chart2" style="height:300px; width:500px;"></div>

<pre class="code prettyprint brush: js"></pre>

<p>Coming straight from the same bakery, donut plots have nearly identical options as pie charts.</p>

<div id="chart3" style="height:300px; width:500px;"></div>
