That graph Does contain bees.

To be specific, bees are a “Cladistically included but traditionally excluded taxa” of wasps, since they are within Apocrita.

The common-language definition of wasp is literally “A member of Apocrita … except bees (and ants)”.
It’s the same situation as saying a chicken is a dinosaur, and why the field often uses “non-avian dinosaurs” instead for clarity.

Further, the typical wasp, the yellow-jacket, is actually way closer to the bee within Apocrita. Take this wikipedia diagram from the Aculeta article:

So if you want to exclude wasps and bees at the level of Apocrita, you’d have to turn yellow-jackets into bees.
