An SVG Line chart inspired by a chart on the NVD website

This is a demo of a Line chart that was "inspired" by an example that was showcased on the NVD website. It's a filled Line chart that has the filledAccumulative and the spline options enabled. And importantly, the first color for the chart is transparent - making it seem like the rest of the datasets are "floating". The rest of the configuration is quite straight-forward - the vertical grid lines are turned off and the colors are a custom set. There's also labels specified.

This goes in the documents header:
<script src="../libraries/RGraph.svg.common.core.js" ></script>
<script src="../libraries/RGraph.svg.line.js" ></script>
Put this where you want the chart to show up:
<div style="width: 950px; height: 250px" id="chart-container"></div>
This is the code that generates the chart:
    new RGraph.SVG.Line({
        id: 'chart-container',
        data: [
        options: {
            filled: true,
            filledAccumulative: true,
            colors: [
            spline: true,
            backgroundGridVlines: false,
            backgroundGridBorder: false,
            xaxis: false,
            yaxis: false,
            xaxisLabels: ['01','02','03','04','05','06','07','08','09','10','11','12','13','14','15','16','17','18','19','20']
