The journey planner site also has usage timeline chart, but not nearly as well presented as this. I despise the tube rush hours, I won't get on before 9:15am, and not before 6:30pm. I will happily watch over-crowded trains go by, and will get off a train the moment it starts crowding. I don't care what my boss wants. This information is useful for adjusting habits as time goes by and things change.
