Hi Vid,
Like @ukmoose already explained, the flow editor isn't a dashboard. So this kind of stuff isn't really encouraged. If you really need to show custom content, have a look at this link. Some remarks:
- Also have a look at Nick's reply to that post: the used API is not public, so it might not work anymore in a future version!
- The node-red-contrib-image-output node displays it's own SVG content inside the SVG of the flow editor. So if you need to display HTML, I assume you might need something this. But I haven't tried this and I have no experience with it ...
