Deeper Diagrams.net Integration

Hi,

I saw that Diagrams.net integration existed in outline, and that's cool! However, I noticed that the integration isn't all it could be: it simply takes an external diagrams.net URL to display the content (as an iframe I assume).

Dragrams.net's [integration features]( (EDIT: [technical documentation here]( allows for PNGs with embedded diagrams.net data to be used as a data source. This means that Outline, rather than outsourcing the document generation, could instead use self hosted images. This means no URL needs to be specified and editing of the diagram can be done without leaving the application.

You can see this integration in action with bookstack:

Would this be considered as an option for a feature request?
(PS: if yes, also add an environment variable for the Diagrams.net URL. Some of us self-host diagrams.net as well).
