A Thermometer chart with a mousemove event driven tooltip

[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.thermometer.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="100" height="400">
    [No canvas support]
This is the code that generates the chart:
    new RGraph.Thermometer({
        id: 'cvs',
        min: 0,
        max: 100,
        value: 68,
        options: {
            tooltips: ["It's getting hot in here!"],
            tooltipsEvent: 'mousemove',
            textAccessible: true
