Why the labels? The graph is only worth anything if the links are trusted. Facts taken straight from a federal filing are ✓ from source; figures we calculate are ≈ computed; links we infer (corporate parents, districts, competitors, connections between records) are ≈ inferred, worded carefully, never asserted as fact and never a claim that one thing caused another.
