Here’s the first map I’ve made in some time outside the Star’s resources – it went pretty smoothly.
The map shows ridership by subway station, taken from this document, which lists ‘the typical number of customers travelling to and from each station platform on an average weekday’. The circles were sized by defining the radius as 1% of this number as metres, so that for example Union, with 102,160 passengers a day, got a 1021m-radius circle, and so forth.
I’m open to a discussion of whether this makes sense as a graphic design strategy: 1) Bloor/Yonge’s circle stretches from Eglinton to a point in the harbour about a third of the way to Ward’s Island; 2) from what I dimly remember from high school geometry, the differences between stations are probably being visually exaggerated by expressing them as circles. update: see comment
As for the actual data, I wasn’t aware how little traffic there actually is on the Sheppard line – you will have to zoom in four levels to see Bessarion at all clearly.
