Hello,
I just discover Telescope and I hope such a tools wiil be soon available in Joplin.
A good example of numerous notes using statics pages is available here.
Have a look !
Telescope allows you to aggregate documentation in a non-hierarchical way. Unlike a wiki where everything is linked vertically, with Telescope, you link the records using keywords, which then allows you to generate a graph, in which it is possible to navigate without going through the tree structure of the notebooks.
While browsing the forum to find something like, I discovered this old post "Mind Map" in which psophos talks about Obsidian.
So, i try Obsidian with my Joplin notes. I got a graph, but showing the uggly file names wich are guid in Joplin 
I also find this post : "Link Map" as a similar feature request.
I'm sure if Telescope was properly integrated into Joplin it would be possible to have an even better note management tool.
