  on hover box. Note that this will override `hoverinfo`.
  Variables are inserted using %{variable}, for example "y:
  %{y}". Numbers are formatted using d3-format's syntax
  %{variable:d3-format}, for example "Price: %{y:$.2f}".
  https://github.com/d3/d3-3.x-api-

  (the ones that are `arrayOk: true`) are available. variables
  `count`, `probability`, `category`, `categorycount`,
  `colorcount` and `bandcolorcount`. Anything contained in tag
  `<extra>` is displayed in the secondary box, for example
  "<extra>{fullData.name}</extra>". To hide the secondary box
  completely, use an empty tag `<extra></extra>`.
