Screenshot of Podroll Atlas zoomed all the way out, showing the entire ~33,000-podcast graph as a phyllotaxis spiral on a black background. Most-recommended podcasts cluster as larger, brighter dots in the dense center; the long tail spirals outward in a sunflower-like pattern of small colored dots. The left sidebar shows 33,069 nodes, 28,300 edges and the full How-to-use legend. A hover tooltip in the top-right reads "The Diary Of A CEO with Steven Bartlett — flightcast.com · recommended 176×", and a faint cyan line traces from that node toward its position in the center of the spiral.

Thanks @dave for releasing the open datasets from PodcastIndex: so much fun stuff you can build with them! e.g. I prototyped a Podroll Atlas, running entirely in your browser:

Wishlist: if the recommendations dataset shipped the full array of sourceFeed IDs and URLs the graph would get a lot richer with clusters, fan-in, communities.
