Refactor: first-class support for plot "views"

[vladsavelyev]

Description of feature

Currently, each plot is assigned a fixed HTML id used by many JS callbacks. It doesn't work well when we have switch buttons to toggle "views" of a plot - like the violin/table switch where we have to add a violin- prefix to the violin version and handle it properly in JavaScript.

We need a first-class support for sych views. That would also allow us to properly add an export button for tables and handle #2389
