Here’s a library called Paths.js that helps you create SVG paths thanks to a high level API. The resulting paths can be used with template engines like Mustache or Handlebars so you can show graphics (SVG) in any browser.

If on the other hand, you use a static template engine like Angular, Facebook react, or Reactive.js, you can animate these SVG graphics as well.

You can define shapes such as ellipses and polygons in the lower levels, and in the highest levels you can draw charts, pies, sparklines, radars and more.

Paths was created by Andrea Aferretti and you can fork it to improve it, or use it for free.
