A 3D Line chart demonstration

Here's a novel new demonstration of a chart: A 3D Line chart with multiple datasets. This is not a natively supported type of chart though the code to create it, whilst big, is not complicated and it's fully annotated so you should find it easy to follow.

The next release will feature it as part of the demos that come with RGraph which are located in the demos/ folder and it will be called: demos/line-chart-3d.html. Here's an image showing it and you can see the demo in its full glory by following the link below to a codepen of it.
