Can a tooltip be added as well when hovering on the cell ?

Hi,

I just started using this and it has a very cool visualization interface.
Would be great if you can add the following feature:

If the number of classes that are present overall is big (say 200-250), it becomes difficult to read the message that is displayed in the place of "Hover over cells to show more information." , as you have to scroll left and right continuously.
So, is it possible to also include a tooltip with the onhover of the matrix cells to easily show this information? Or somehow have the message dynamically centrally aligned so that the user does not have to go back and forth all the time on the screen?

Have added a screenshot that I am talking about.

Thanks!

Thank you for filing this issue! That's certainly something that we could integrate, I'll open a PR once it's ready.
