This caught my attention because of the mention of MS Visio. I used to use it quite a bit back in the day. And I think a web port is a terrific idea! Honestly, if you can teach yourself the basics. Your main tech challenge domains will be network and canvas rendering runtime debugging. Take a look at High Performance Browser Networking https://hpbn.co/ https://hpbn.co/ And Google's series of Udacity courses on building performant web apps https://www.udacity.com/course/browser-rendering-optimization--ud860# https://www.udacity.com/course/browser-rendering-optimizatio... Best of luck ;)
