Programming , mostly . As my understanding of data science goes , it encompasses both statistical and machine learning knowledge , as well as programming in r or python for data manipulation , applying models and visualisation . Also , it is trendy . <| sep |> I did make a similar chart awhile back where I added in markers for every update so you could see how the player numbers were affected by updates going up before updates , dropping down after updatesThis one only shows up to the Everheart build , but it includes both average and peak numbers , with the markers for each update month the update was releasedGraph showing the different updates compared to player numbersKeep in mind though that player numbers are not exclusively affected by the updates released for the game . Outside factors such as summer and christmas holidays show notable drops in amount of players and other things such as other hyped up games being released can also negatively affect player numbers . So don ' t just look at the numbers , e . g . after Utz build , and blame just the Utz build for player numbers dropping .
