Right now each point is of a team. This isn't incorrect but it does cause issue where two teams share a stadium (you get two points in same location). A stadium does not need a team to exist but currently this is the case.
We need to pivot the data so that each point is just the stadium and then list the teams under each stadium.
I have a github...hahaha i don't use github. I almost sent you an email for this but decided to put it here. I'm a non-JSON user, so this is more about JSON - are you up for related tables about ballparks? I was thinking about the River Cats here and how a few years back they went from the A's feeder team to the Giant's feeder team, in the spirit of learning about JSON...can that be done? Also, if the answer is yes then maybe i'll do a related table between AAA and Major League teams. :)
