Ideally, I would like the diagrams to be hosted somewhere, instead of attaching them to an Issue as described here:

https://stackoverflow.com/questions/14494747/add-images-to-readme-md-on-github

Also, this might be asking a lot, but it would be nice to have these images (preferably SVG) remain editable (similar to a Visio diagram) that I can put Auth in front of (since I would like to use it for my company too).

Does something like this exist?
