Adding diagrams to Blog posts and Wiki documents as living objects (edit and change directly from the Connections editor) would extend the possibilities of working together on text and diagrams without the need of installed software and export this as graphic.
Other Wiki engines have the possibilities to add diagrams and edit them directly. Adding and rendering diagrams extend the functionality and user experience a lot and would close the gap to competitors.
To achieve this they implement the free tool draw.io (https://drawio-app.com/integrations-ecosystem/) or maybe easier implement a way to use https://mermaid-js.github.io/mermaid/#/. So no need to develop something, just an integration point would be needed.
Mermaid should be easier, because it renders diagrams in
<div class="mermaid">...</div but the editors in Connections convert entities like < or > to the html entity and the mermaid js need the characters < > .
So it would be enough to add an option to disable entity conversion and users can easily add diagrams (gant, flowcharts) to their documents and change them on the fly in the Blogs or Wikis editor.
