Web-based WF workflow designer

Microsoft's WF is a good workflow development platform. Compared with the Open-Source Workflow implementation, its designer is not very beautiful (of course, this is also quite different from the connected designer I have seen before.) I suddenly came up with an idea last week. Can I implement a similar workflow designer on the web page ?! We all know that it is difficult to draw a line on a web page using JS (in fact, it is impossible to draw a line, unless it is simulated by N Div elements ), however, the WF workflow designer is very easy to implement on the web page!

With this idea, my first reaction was to check whether someone had done similar work in online search. In view of the previous "painful" experience: generally, I have already come up with some ideas! Sure enough, let me find a http://www.netfxlive.com/But fortunately, my previous thought was done by someone N years ago. This time it was just a few months ago and it seems like a work under development! But it's pretty good. I like it!

The following is what I achieved by myself like it. At present, it is far behind the function, but the interface looks similar, huh, huh!

If you are interested in how to implement it, go to the URL provided above, save the page as, and then you'll just look at it, huh, huh!
