A Pie chart with tooltips

[No canvas support]

This goes in the documents header: 
<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.common.tooltips.js"></script>
<script src="RGraph.pie.js"></script>

<style>
    .RGraph_tooltip {
        padding-left: 0 !important;
        padding-right: 0 !important;
        padding: 10px !important;
        font-size: 16pt !important;
        font-weight: bold !important;
        text-align: center !important;
    }
&ly;/style>
Put this where you want the chart to show up: 
<canvas id="cvs" width="350" height="250">
    [No canvas support]
</canvas>
This is the code that generates the chart:
