This infographic was prepared for the d3.selectAll('meetup').data([2014]).enter() meet of the Bay Area d3 User Group, held Jan. 28, 2014. It uses Mike Bostock's Circle Packing enclosure diagram to show the long-tail distribution of authors and titles in the D3 ecosystem. Source data originates from the D3 Gallery spreadsheet.
During data cleanup, aggregated domain values were assigned to each record in the data from the url. The bl.ocks.org domain represents 880 titles, and github holds 169. However, there are 24 domains with more than 5 titles and another 522 with fewer than 5. While bl.ocks and github are the foundation for the developer community, the other domains hold finished titles that make points and change opinions. Presentation of author titles by domain allows us to see this dynamic at a glance.
Each containing circle (yellow) represents a web domain where authors display their finished D3 visualizat
