I wanted to make an interface where I could interactively create a flow chart/graph and save it to a data table to be operated on e.g generate quizzes based on graph traversal etc.
I am quite new to anvil so I wasn’t sure if there were any client side options for this that were free, so I started to try and make one. I probably should have used neo4j and some front end stack to do this.
That’s great @chongdtwdavid94 I was wondering how to do something similar.
This is what I had in mind Drag & Drop.
As used in Funnelytics and others
I used the canvas component and the associated events and drawing functions. Its not quite done yet, like I haven’t got round to implementing arrows for directed graphs and formatting the edge texts nicely etc.
This is really cool! When you finish it, please do post an update 
(and Tweet it, if that’s your sort of thing…)
I’m looking forward to this. Node-RED (https://nodered.org/ ) has a powerful browser-based flow Javascript library that makes for me the case to adopt Anvil compelling. There’s also a related Node-RED uibuilder project (node-red-contrib-uibuilder (node) - Node-RED) that’s apparently easier to use. Unfortunately, I don’t have the technical chops to code the ‘escape hatch’ - as Meredydd eloquently described in one of his posts.
Dear chongdtwdavid94,
That’s cool stuff! Also interested. I want to build engineering concept diagrams and connect them to automatic calculations. Let us know whenever you’ve made some extra steps!
