For Graphicacy's Major League Data Challenge, Eli Shayer, Scott Powers, Daniel Alvarado, Stephen Spears, and I created an interactive visualization for the careers of the MLB's top 10 hitters and top 10 pitchers of all time (by Wins Above Replacement [WAR]).  Our submission won 2nd place in the challenge.

The visualization is embedded below.

This work has been presented at a meeting of the Stanford Sports Analytics Club and a meeting of the Bay Area d3 User Group.
