Add diagrams for dependent origin

After some research and experiments, sunburst diagram with zoom is NOT a good fit

In fact I don't think it's a good idea to have a circle or a ring like structure, it's too hard to read, though fancy.

We should have a diagram just like the citta flow chart. This is not a complex diagram, we just need to emphasize each node or link when viewer highlights them.
