Eric Fischer, a developer at the map building company Mapbox, has created a map visualizing geotagged tweets around the world from the past three and a half years—all 6,341,973,478 of them. The visualization plots all tweets tagged with location data, which is about 120 per second, or about 10 million per day. Fischer used Twitter’s public application programming interface (API) to compile the three terabyte dataset, which grows by four gigabytes every day.
