Prototype your Scenic UI scenes in Inkscape or other SVG editors, then quickly fire it up in Scenic for display (I do a Process.sleep(1000) and re-render). Or generate code/data representing Scenic primitives that you can then hand-modify / cleanup to your needs for final deployment.

While Scenic.FromSVG can alreay display SVG pretty well, by translating SVG to Scenic drawing primitives either at runtime or compile-time, it’s not intended to be a general purpose SVG viewer.
