The basic premise is that there should be some graphs to show a user's growth over time. Kind of like The Pokebay Stats in profile shows income breakdown. 📈
Similar graphs to show global points/ranking/overall exp etc. Now, Idk if this is possible or even if historical data is kept somewhere. 
The major problem would be that the stats keep changing all the time. An implementation I have seen in other games is that they take a snapshot of a user's stats at the start of the day and use that data for visualisation. 
chill bruh
