hoverSelects ideas

[tdhock]

The current barrier to implementing aes(hoverSelects) is that we don't have any way to test it using RSelenium ropensci/RSelenium#59

For single selection variables I propose that mouseover should call update_selector and mouseout should do nothing.

Would it be useful to combine hoverSelects with a multiple selection variable? Anybody know of any examples?

Are you thinking that mousing over would set the selector to on then mousing out would reset the selector to whatever it was before?

If so, then hoverSelects could be useful for any viz with multiple selection and lots of groups as a way to easily highlight just one group? The world Bank viz for example. Does that make any sense?
