A graduated dark Line chart

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.line.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="600" height="250" style="border-radius: 5px; background-color: black">
    [No canvas support]
</canvas>
This is the code that generates the chart:
<script>
    new RGraph.Line({
        id: 'cvs',
        data: [
            [120,123,121,120,125,122,121,120,118,116,113,114,111,108,106,118,124,123,120,134,135,115,116,125,132,153,148,151,165,164,166,171,178,175,176,179,181,183,183,185,188,189,210,213,220,184,186,145,156,149,132,135,132,133,128,129,126,123,122,115,101,213,256,255,248,245,240,238,233,212,245,255,251,233,251,212,156,157,184,189,194,194,192,201,200,203,214,228,264,233,264,254,258,251,235,239,233,212,244,241],
