I only looked at your site for a bit, but it looks perfectly decent. The graph view was there, if via the side button slide-out, but it works well. Considering you are saving ~$100/year, I would say it looks great. Wishing you the best.
I did see this work around for publishing to a blog with another free md editor. Of course, you have to have a blog and I suspect that would cost as well to be able to use such functionality.
Personally, I have a website and I am going to wait for the Obsidian wordpress plugin. I had a vision for doing this same type of distributed wiki-like publishing on my site, but before finding Obsidian it was going to be very labor intensive to link everything.
