Hey everyone,
Thanks very much for your responses.
Coming back to this, I've found I still haven't found the solution I am looking for, as Google links to something else than I was hoping for.
Basically, I am not looking for a plug-in to visualize a graph, based on a certain indentation structure of a plaintext document being edited in Vim. The plaintext format is fine, for my purposes.
Rather, I am trying to still make that plaintext that I am editing in Vim have certain properties that make it more fundamentally like a mindmap. Most importantly, text should be bounded within certain regions. In effect, text should be contained within text boxes. You cannot write anywhere you want in the file. You can only enter text into text boxes, or whatever Vim's representation of a text box, to the same effect, is.
I would like to believe this is possible since Vim is so customizable. And I want to do it in Vim since increasingly everything I'm doing is in Vim.
So, is there any way to create a text box in Vim? I could just draw boxes with lines, but the deeper point is having Vim recognize that a box is an object or region where text is permitted, and blocking the entry of text outside of that object.
I'd really appreciate any help on this.
Thanks very much,
Julius
