BTW: the original of the Google Doodle is, as usual, interactive. One may choose a category of thing and a characteristic. The Venn diagram is then formed to show the intersection thing category ∩ characteristic.
P.S. have a quibble with the illustration of transport ∩ has wings. The Doodle shows only an airplane. Why not a rotor craft? Just because its wings rotate doesn't make them ineligible.
