Feedback request for my project "D3 Graph Theory"

Hello everyone!!

I am a JavaScript beginner and I have been working hard on a project for over a month.

D3 Graph Theory is a project meant to be used as graph theory tutorials.

I believe there must be performance and design issues with it. I wish to make it a better tool so that people can actually utilise it.

Please check the above mentioned link and tell me whatever thoughts and opinions you have on my project. It could be about anything like design, content, code, bug, etc. I even value your critical opinions.

If you wish to go extra mile and check/review my code, then here is the link : Github Repository of my project

Thanks a lot.
