Healing Recieved Graph

As a support main, I think it would be cool to have a graph at the end to see the amount of healing you've recieved from allied champions. Especially as , , , ,it would be fun to see who you healed the most. Idk if this idea has been brought up before, but I think it sounds cool. Only problem I see is that there aren't a whole lot of champions that heal other champions.
