build a basic structure

I published the backpropgation graph. I commented out the mlp one because it is too large. It may require some kind of styling.
It just has HTML, javascript, and CSS.

This one only took me a few hours to finish it, not counting a day looking thru this repo. However, I originally do it in HTML dom because you suggest not to use npm. But I found out it is way easier to do it in React.js. With it, we just import certain graph library from javascript and break the complicated HTML as object orietant.

I guess this pull request is pretty much a proof of concept for other people who want to add this into this repo. Again, all are done in Javascript. No Python. If you want, we can change it to type script with "type".

I have 2 version of graph. First one is using React Flow:
It is good, but it has a logo if we don't use their pro-version

2)
For the mermaid, it just doesn't work when I deploy it on github.io.
But it is totally fine on other places , such as Netlify.
Although React Flow is very powerful, I guess AJ doesn't like the react flow logo on the graph.
For the mermaid one, I guess it is not necessary to upload it to github.io

I guess I will pick mermaid one.
