How to graph an Oval on a geographical Map

BLUF: I'm trying to graph an oval on a matlab map using something like geoscatter.

I have data for 6 points, each of these points has a latitude and longitude with each of these having a standard deviation (in miles) associated with them.

Also, the standard deviations are in units of miles also.

I may not be explaining it well enough but I am lost on how to proceed here.
