clickable data-points in graphs

something like

ggvis() %>%
  ...
  handle_click(utils::browseURL("http://www.r-project.org")) %>%
  ...

should/could somehow provide clickable data-points.

The episode url is contained in the show.episodes object, so one would assume it should be easy to point the click event to that episode url, and one would be wrong.

The url variable is not contained in the vis object created by ggvis(), and the key := assignment is already used for the tooltip (and will be use for the full-fledged tooltip soon™), so… I have no idea how to get that data in there.

Also, I think a browser won't understand utils::browseURL 😸
