This project applies data visualization techniques seeking to contribute to the studies conducted at the Tecgraf Institute at PUC-Rio. These studies have focused on assisting the Flamengo basketball coaching staff in measuring and analyzing the impact of lineups on the team s performance during games and understanding the causes of this impact (positive or negative), taking into account the participation and collaboration among the athletes. To achieve this, a web application was developed capable of generating graphs that condenses various information and enabling analyses that were not possible before.
