Support IATA airport code to display cities on the world map?

[izzyleung]

Hi,

I was wondering if you guys will support using the IATA airport code to represent a city and display them onto the world map (probably user will be able to zoom in and out).

I am trying to integrate this function into my dashboard using Google Maps's heatmap, I would be very happy if you guys can help to make it possible to make this function available for Caravel.

Thanks in advance for your reply.

You'll need lat/long, but this PR is a good preview of what is to come:
