tables to your pages. It can be used whether you use the
canvas or SVG libraries or entirely standalone.

Written by Richard Heyes, RGraph author, on 3rd September 2015
As stated elsewhere canvas paths are (unnecessarily) verbose. The W3C has attempted to
aid the issue by introducing support for svg paths in the new Path2D object.
This new object, however, is not currently widely supported. So RGraph provides a
work-around using the RGraph.path function.
This is a description of that function and a version of it that has been extracted from the RGraph code and works standalone.
