Updated to include team names. - ed
In my last post I tried to dive into some more complex (read: confusing) methodology and, though the graphic turned out to be quite pretty to look at, there were some flaws in the data behind it. So, for my next project, I decided to stick with something more simple and fun.
For those wondering about the very nit-picky details of how this was put together, I'll explain a few things. I chose to go with a game-by-game method instead of day-by-day method simply because that data is a) easier to find, b) easier to understand, and c) smaller, which equals less time you have to spend looking at this thing. However, it does make things a little funny because off days mess with the perfect order of things. For example, it is entirely possible for both the Padres and the Giants to have a .5 game lead in the division in game 154, because those two teams played their respective 154th games on different dates. Everything else should be pretty simple.
