Default A day on the London Underground - visualised by tracking Oyster cards

Err the data is 500k journeys on weekday. Probably about 1/6th of
average weekday patronage back then.

Notwithstanding your other points, if it's a random sample of 1/6th then
the fact it's not 100% doesn't matter at all when visualising relative
usage from one line to another.
