Abstract
In sports like soccer, with lots of player and ball movement in the game, spectators usually only roughly brasp the flow of the game as a whole, and focus specifically on the characteristics of the team.
During a game, we may basically understand team ball possession by physically watching; however, we can understand it logically by analyzing play data during the game. Constructing an application for such a purpose, easier visualization of the overall game flow, by calculating possession rates from soccer play data, would be extremely helpful; and RStudio would be a good tool. Thus, we made a visualization application that can easily measure many games by using manipulate function and Shiny of RStudio.
