I would like to hover over a DC.js canvas chart, and use the hovered point to apply changes to another chart (I.e. display the information about that point in another chart).

The complications:

* It's a canvas plot I'll be hovering
* The whole thing needs to be done within the context of a virtual DOM

I'm guessing it will be a renderlet like [this](https://stackoverflow.com/a/34798270/12728698), but it's rather tricky as it's a canvas plot.

I'm assuming the fact that it's canvas will require me to use a hidden element, like in this [block](http://bl.ocks.org/Jverma/70f7975a72358e6d69cdd4bf6a0569e7)

I've put a [Stackblitz](https://stackblitz.com/edit/react-ts-mw2pg1?file=components%2Fdc%2FEventScatter.tsx) up where the required behavior would be hovering the orange and green plot, and the other scatter is has some (any for this example) property changed for the respective group point
