I added an SVG-based totally native EWB line graph (multiple lines) component (so no linked javascript).

There is a demo at: https://www.erickengelke.com/nice/samples.html

I needed this to solve the problem of small or compact graphs not being easily created with existing tools, and the awkwardness of other solutions.

Anyone with an existing Nice Libraries license can just download the latest updates.
