Round the map coordinates for World Map Interaction answers

What steps will reproduce the problem?
1. View content statistics for the oppia.org Exploration "Welcome to Oppia" for 
the state named "Finding Helsinki".

What is the expected output? What do you see instead?

Expect: summary of commonly selected locations.
Actual: the coordinates shown are so precise they can't be summarized. 
(examples below)

What operating system are you using?
OSX / Chrome

Please provide any additional information below.
- See attached screenshot. The coordinates provided by Google Maps API have so 
many decimal places of precision that they can't be summarized to a useful "top 
5" locations summary.  As such, none of the top answers match more than 1-2 
times despite 5,000+ learners reaching the page.  Example coordinate precision: 
45.460130637921004,46.845703125

Suggested solutions:
1) Easier: perhaps consider rounding coordinates to the nearest hundreds or 
thousands places (though would that be losing too much precision for cases 
desiring street addresses?)
2) Better: rather than displaying coordinates (which may not have much 
immediate meaning to human reviewers), if Google Maps API has the ability to 
return a "nearest known city" string it may be best... (though specific to this 
state which is focused on cities). Another option might be returning a "nearest 
known address" string if Maps API can do it.

I suggest not looking at this yet. Maybe take a look at the issues labelled “LaCE Quality Team” and see if you find one that you can tackle?

Stats/ Summary for “Finding Helsinki” looks like this now. Wanted to check if any change is expected before diving deep into this 7 year old issue. Can someone let me know as I am looking for a good second issue?
