A basic SVG Pie chart

A basic SVG Pie chart. The chart uses tooltips which have the outline style of highlighting and it also has a key - which can be used in place of labels in order to be able to tell what the segments represent.

This goes in the documents header:
<script src="RGraph.svg.common.core.js"></script>
<script src="RGraph.svg.common.key.js"></script>
<script src="RGraph.svg.common.tooltips.js"></script>
<script src="RGraph.svg.pie.js"></script>
Put this where you want the chart to show up:
<div style="width: 650px; height: 350px" id="chart-container"></div>
This is the code that generates the chart:
    new RGraph.SVG.Pie({
        id: 'chart-container',
        data: [1,1,1,1,1,1,1,1],
        options: {
            tooltipsEvent: 'mousemove',
            highlightStyle: 'outline',
            labelsSticksHlength: 50,
            tooltips: ['Alf','Berty','Craig','Dean','Elgar','Fliss','Lucy','Paul'],
            key: ['Bob','Rik','Alf','Hal','Kev','Tom','Mat','Pam']
