An SVG Line chart using transparency

This is a Line chart that has some custom values applied to it. It's a filled chart, also using the filledAccumulative option too so the datasets are stacked one or top of the other. Gradients have been given to the fills and different colors given to the strokes. It's also using the trace() effect.

The gradients that are used as the fills aren't used for the stroke colors of the lines - those are separate green and blue (they aren't set specifically - but rather using the defaults instead.

There's a canvas version of this chart (line-filled-dark-trace-sequential.html) the download archive where the datasets are traced individually and sequentially.

This goes in the documents header:
<script src="RGraph.svg.common.core.js"></script>
<script src="RGraph.svg.line.js"></script>
Put this where you want the chart to show up:
<div style="width: 750px; height: 300px; background-color: black" id="chart-container"></div>
This is the code that generates the chart:
<script>
    new RGraph.SVG.Line({
        id: 'chart-container',
        data: [
