The series hover interactivity uses the technique from lgrammel seen here: http://bl.ocks.org/1963983
It isn't necessarily a tooltip, but data is displayed by inverting the x-axis value into a date, and mapping the date to the corresponding data value for the series.

| # git-mv-with-history -- move/rename file or folder, with history. | |
| # | |
| # Moving a file in git doesn't track history, so the purpose of this | |
| # utility is best explained from the kernel wiki: | |
| # | |
| # Git has a rename command git mv, but that is just for convenience. | |
| # The effect is indistinguishable from removing the file and adding another | |
| # with different name and the same content. |
