Geographical plot of the spatial distribution of all Spanish tweets in Buenos Aires.

Each circle corresponds to an individual bin and its size represents the number of tweets in that bin. (A) Distribution in the greater metropolitan area of Buenos Aires (CABA+) which is sub-divided into 100 x 100 bins. (B) Distribution in the administrative boundary of the city of Buenos Aires (CABA)–delineated in black–which is sub-divided into 75 x 75 bins. Both distributions show greater tweet counts in the more population-dense regions corresponding to the downtown area (upper-right quadrant of (A)). The total number of tweets in the CABA+ and CABA extents were 1,930,987 and 1,065,614, respectively. Base map and data from OpenStreetMap and OpenStreetMap Foundation under the Open Database License.
