The 95 Braves

A bubble chart is a scatter chart where the size of the bubble represents a measure. This allows us to track three separate measures on a single visual. In this case, we will track the relationship between on-base percentage (OBP) and batting average (AVG) for players, using the number of at-bats (AB) as the size of the chart. On-base percentage is an "extension" of batting average: with batting average, we track how many hits you had over at-bats. With on-base percentage, we add things like walks and hits by pitch to both the numerator and denominator. Therefore, AVG and OBP are very highly correlated.
