That's quite a weird issue that you're experiencing. This is due to the
GeoChart trying to be smart when it tries to geocode things. Essentially,
when we send data off to the Maps API to geocode, we try to give Maps a
little bit of context. This context turns out to be the region that you've
specified in your data. For the US-IL case, this makes the request look
something like "PEKIN US-IL" or "Peoria US-IL", which maps uses correctly.
However, when you use "US-675", that makes the requests look like "PEKIN
US-675" or "Peru US-675", which Maps doesn't seem to handle quite as
gracefully. Some of the areas you gave wind up geocoding to Mexico, others
to Colorado, etc. A possible answer here is to use the bounds of the map as
well as the region code to bias the results toward your relevant area. I'll
take a look into doing this, but unfortunately I can't give you an
immediate fix outside of geocoding the points yourself.
