#### Describe the issue that you are seeing, or the feature request :-), include any screenshots as necessary.
Elastic search has a geo_point and geo_shape feature types that are best presented on some kind of map. It would be great to be able to see them either as another tab opened a tooltip or a popup dialog.

As a side note, I'm using ES for sometime and just found out about this UI, and it is great - truly a missing UI, I don't understand why ES doesn't support this out of the box...

The issue names no files, tests, or entry points. Start by locating the existing field display and tooltip or popup views in the Chrome extension, then determine how geo_point and geo_shape fields are represented. Done means presenting those geometries on a map through a tab, tooltip, or popup dialog.
