4 years ago @xcaeag, this looks like what I'm trying to do. I'm just looking for something to use for making a single diagram. Too bad no one ever responded (as far as I can tell) to your PR offer. I did find your fork at https://github.com/xcaeag/raw. I haven't tried it. I haven't used rawgraphs either. So I have no idea how much of a time sink I'll be getting myself into. But thanks! And thanks, rawgraphs team, for all the work you did. It appears to me that there's probably still a need for it.
If it interests you, I have a rather simple piece of code that draws the links in color gradient.
Another adds the names of the different steps in the boxes. If you wish, I can do a PR. Initial working is not changed, two parameters have been added.
