I produced a little interactive with D3 which shows some tooltip text when hovering over the datapoints. I would like to allow users to copy the text in the tooltip (or simply use all of it) to share via Twitter. The problem is that I can not fix one datapoint because it changes when I move over the graphic. So I would either like to freeze the tooltip text for a couple of seconds, so that it doesn't immediatly change on hover OR have another option (maybe on click or rightclick) to share the sentence via Twitter. Any idea?
Here is my working code so far:
