Green Area (Offensive Coverage): Shows how many Pokémon in your team have moves that are super effective against each type. Larger area = better offensive coverage.
Red Area (Defensive Vulnerability): Shows how many Pokémon in your team are weak to each type. Larger area = more team members vulnerable to that type of attack.
How to read: The scale (0-${6}) represents the number of Pokémon affected.
For example, if the red area extends to 3 on the "Fire" axis, it means 3 of your Pokémon are weak to Fire-type moves.
Ideally, you want a large green area (good coverage) and small red area (few weaknesses).
