BARTagonal
July 8, 2010
Hmm. Dulay Lines? Or a little known piece by Theo van Doesburg?
Fans of Tufte will immediately recognize it. If you guessed something transportation related, you are correct. The great dataplotter Eric Fischer has once again wrangled meaning out of a hapless API: The chart above shows BART train movement between Millbrae (top) and Richmond (bottom) between 7:30 AM to 9:30 AM on July 2. The entire day along with Eric’s comments are available on Flickr.
(I find the thought of a Muni version of this chart mildly terrifying.)
On a side note, Eric is in print! His tourist vs local mapping made the Boston Sunday Globe! Congratulations!

Thanks! I would like to do one for Muni too, but it’s complicated because there are so many routes and so many vehicles (and no guarantee that the vehicles are even staying on the published routes). Maybe I should start with something simple like the California Cable Car that never even turns any corners.
I was thinking just a few lines. Maybe the 14, 1 and 38, if only to see the slope.
14 vs 14L would be interesting.
I sort of got it working! Here is a day of the 1 California — http://www.flickr.com/photos/walkingsf/4789579290/ — and with luck I’ll get some other routes plotted soon.
