Description
What? I’m a refugee from Atom and I’ve been thoroughly enjoying my experience with Neovim so far. I’m down so a scant few of my favourite Atom features I’ve yet to find answers for with nvim. One of those features is atom-regex-railroad-diagrams 2. With this atom plugin installed, any time the cursor is on a regular expression, a graphical railroad diagram 4 appears at the bottom of the window.
Is there something comparable for neovim? Surely, terminal-based plugins would have to use ascii art or something like that, but perhaps something could be done anyways?
Some cursory googling didn’t turn up much, there’s too much history with vim and regexp search terms to break through the noise of ‘how to regexp in vim’ tutorials.

Why? Regexp is confusing, railroad diagrams help
Potential existing implementations:
inccommand- https://github.com/tabatkins/railroad-diagrams/issues/94 could be adapted to output text
Potential pitfalls:
issue linked above - railroad-diagrams library could be adapted, but it wouldn't be trivial
