| 説明 | I think this is the most informative version, even if it doesn't look the best, since by routing around frequency it keeps from drawing, for instance, San Francisco to San Jose trips on top of trips to and from SFO.Lots of travel between San Francisco and various South Bay locations; from SFO dispersing north and south; from Sacramento to San Francisco and San Jose; and what looks like a lot of trips between San Bruno(?) and Santa Cruz.From all available journeys recorded in pairs of Twitter geotags near the San Francisco Bay Area though October 21, 2011. |
