Hey Product Hunt 👋 A few days ago PodcastIndex released open datasets, including one mining the "podroll" RSS tag: that's the Podcasting 2.0 way for a podcaster to publicly recommend other shows from inside their own RSS feed. I turned it into a navigable graph: each dot is a podcast, click any of them to see what it recommends (cyan arrows) and who recommends it (pink arrows). Search a title and the camera flies to it. ~33k podcasts, ~150k edges, runs entirely in your browser via Canvas + D3. No backend. Stack: vanilla HTML/CSS/JS, D3 (for force, zoom, and quadtree), Canvas 2D. IndexedDB caching, 24h TTL. Source is on GitHub, CC BY 4.0.
