Custom tooltips for scattergeo choropleth map

By default the tooltips on the Choropleth (type: scattergeo) maps look like below >>

  • Can we make some style changes on the tooltip:
  1. adding some padding on the tooltip box
  2. make the tooltip box border rounded
  3. Change the tooltip box border color or background etc.

Please let me know if there is any API available to do so.
