The purpose of this project was to create a data-driven animation showing the changes in UFC fighter rankings over time. The Ultimate Fighting Championship rankings was first introduced in February 2013. The votes are generated by a panel of media members. The media members are asked to vote for who they feel are the top fighters in the UFC by weight class and pound-for-pound. The fighters have to be in active status the UFC in order to receive votes and not facing any disciplinary suspensions of nine months or longer. A fighter may appear in more than one weight division at a time. The champion and interim champion can be voted on for the pound-for-pound rankings, but are not voted on in their weight class since they are already considered to be in the top of their division.
