Traceshot

Traceshot follows the links in a public Hacker News thread, GitHub repository or blog post and draws what it finds as a web: each item is a node, each strand says how sure it is, and every strand keeps the page that stated it. A link both sides state reads Observed, one declared by one side reads Linked, and a match on name alone is marked as needing verification. Pinch, pan and tap a node to see why it is there. It reads public pages only and never writes anywhere.
