    Regarding software, I've found diagrams.net to be incredible for this. Also, I believe a lightweight version of Visio online is now included with O365/M365 (Microsoft adds 'lightweight' Visio web app for no extra fee to Microsoft 365 for business plans)

    https://github.com/jgraph/drawio/issues/774 is the ticket about the SVG FOs. Going to PDF and then to SVG in inkscape is an interesting idea, but then needs a server, that makes it harder for others to set the project up.

    Foreign Object support in SVG is an optional part of the 1.1 SVG. Yes, it's true that only browsers support it in practice.

    The reason for its usage is historic. Originally, this project was the underlying diagramming library only, that uses the SVG DOM for rendering. There was no application and no SVG export, that wasn't a function of the library.

    FOs in SVG gave us the whole range of HTML in shape labels. So, as well as complex text formatting, we used it for tables, complex composites, etc. There a large legacy of shapes that use complex HTML for labels, we can't drop support for those.

    The app itself came later and the SVG export function even later. It was fairly easy to generate because we can take it from the SVG DOM. But, converting HTML to SVG requires parsing the full HTML specification and generating the SVG to maintain compatibilty. This is an horrifically large task, it would require probably 5+ people full time, we don't have that resource.

    I'm not sure calling it SVG is "tacky". It is part of the SVG 1.1 spec, albeit an optional one, it's not like it's isn't SVG at all. But yes, it causes confusion, thus the entry in the README [1], "It is not an SVG editing app, the SVG export is designed only for embedding in web pages, not for further editing in other tools."

    Even using SVG for word wrapping alone, we've repeatedly asked critics how to do that without HTML for measuring the font metrics, we're yet to receive an answer how to do that in JavaScript. We've had plenty of comments pointing out this is wrong, we need a practical alternative thought out in detail.

    If their users all have admin, they could already go buy Visio or Project or any of their competing products from a shop and install it. They could download trial versions from https://www.microsoft.com/en-us/evalcenter/evaluate-visio or https://www.diagrams.net/

    You are conflating "open source" with "open contribution". https://github.com/jgraph/drawio#open-source-not-open-contri... explains it neatly:

    > Similar to SQLite, diagrams.net is open source but closed to contributions.

    > The level of complexity of this project means that even simple changes can break a lot of other moving parts. The amount of testing required is far more than it first seems. If we were to receive a PR, we'd have to basically throw it away and write it how we want it to be implemented.

    > We are grateful for community involvement, bug reports, & feature requests. We do not wish to come off as anything but welcoming, however, we've made the decision to keep this project closed to contributions for the long term viability of the project.
