It would be great to support custom svg xml as an input for the icon component

extend icon to allow in-lining (or file path input reference) for svg xml

Thanks for filing an issue. Agree, it would be nice to eventually support this. For now, you should be able to use web components to inline SVGs: https://google.github.io/mesop/web_components/ - let me know if you run into troubles doing that.

Works like a charm, thank you!

As an update, I created a stand alone component for this https://github.com/ghchinoy/mesop-svg-icon
