Below the title on the graphic is the reasining:

" incl. all Olympic formats or high probability to be {Rugby League and T20 Cricket} ] "

But I confess that in this regard I also weighed taking only the main formats and leaving out 3x3 basketball + beach volleyball.

I could imagine to combine field hockey + ice hockey under hockey (so to say as two formats of the sport hockey).

Regarding tennis, there are only team sports in this chart and no individual sports, even if they have team competitions there, its not considered as a team sport.

For the definition of team sports I refer to wikipedia:
