#1144

I have completed all the modifications. There are some configurations that I don't understand what they do, so I didn't implement them.

• Font size
• Opacity scale

Regarding the "Customizable settings for interaction" part, I currently think it's not really necessary to open up the API. If someone has the capability to make modifications, they should be allowed to modify the original code themselves.

while there are a lot of things to be fixed on this PR, I would suggest to just use canvas as default, and drop svg support to make the codepath simple.
