Drawio has some powerful interactive features to add (custom) links to subpages within the diagram or adding actions for showing/hiding layers. This is especially handy for creating navigatable BPMN diagrams and show sub-processes when needed. (or for SW/System/Enterprise Architecture Modelling ...)

This can be achieved by simple HTML Embedding provided by drawio, but instead of a manual HTML Embedding (with time-consuming round-trip), it would be great to just be able to show the drawio diagram directly as a HTML Embedding instead of a static rendered PNG/SVG image.

Just check this tutorial: https://www.drawio.com/doc/faq/embed-html

And check the options: https://www.drawio.com/doc/faq/embed-html-options

The feature is very easy to test and works great.
