A spline SVG Line chart

Here we have a spline Line chart with multiple datasets. The spline option simply makes the lines curvy instead of angular. There's also a shadow enabled and the vertical grid lines are disabled.

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" id="chart-container"></div>
This is the code that generates the chart:
    new RGraph.SVG.Line({
        id: 'chart-container',
        data: [
        options: {
            backgroundGridVlines: false,
            backgroundGridBorder: false,
            yaxis: false,
            marginLeft: 50,
            marginBottom: 50,
            linewidth: 5,
            spline: true,
            shadow: true,
            shadowOpacity: .25,
