Grab any orb and pull. Use the list to jump to any table, trace how two tables connect, or press Show empty to see what is still waiting to be filled. The strings tighten, whatever it is tied to lights up, and it all snaps back when you let go. Drag empty space to turn the whole thing, scroll to zoom.

Click an orb, or pick a table from the list above, to read what it holds. Bigger orbs hold more rows. Orbs with no string are tables nothing else points to. Click one to see why.
