Not yet, as far as I am aware. And it is really a nontrivial problem to make something like this, that not just looks neat, but works efficient.

(I know this, because I am working on something like that, since quite a while)

I'd be curious what you're working on, or if you have any links that are shareable.

This is a truly hard thing to do. I sometimes use visualization plugins in IDEs, or hand roll visualizations. For example, spit out an HTML page that basically lays out up some textarea columns with sample data between code. But it's usually really, really ad hoc. And of course, very company confidential so I can't share much...

I'm also curious about using something like this d3-graphiz project to, say, animate a sequence diagram: https://github.com/magjac/d3-graphviz - just haven't gotten around to it yet (the demo seems like it could be handy: https://bl.ocks.org/magjac/4acffdb3afbc4f71b448a210b5060bca)

"I'd be curious what you're working on, or if you have any links that are shareable."

Not yet, but soon I publish. Maybe some screenshots I could do till then. From what you wrote above, it sounds like it might interest you, though. Basically, I compile code into flow graphs and blocks, that are navigable with mouse/keyboard - and every element can be edited visually, but also as code. So you still code as you are used to - but also get the visualisations automatically for free. It works, but only with simple code.
