A circular Meter chart

This is a customised Meter chart. The canvas is still the usual rectangle but it has been placed inside a DIV which has a large border-radius CSS property giving the circular appearance.

[No canvas support] Temperature (°C)

This goes in the documents header: 
<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.meter.js"></script>
Put this where you want the chart to show up: 
<div style="width: 450px; height: 450px; background-color: white; border-radius: 250px; text-align: center; font-family: Arial; box-shadow: 0px 0px 25px gray; border: 10   px solid #ddd">
    <canvas id="cvs" width="450" height="350">[No canvas support]</canvas>
    <b style="font-size: 20pt">
        Temperature (°C)
    </b>
</div>
This is the code that generates the chart:
