Visualizations

Seeing the atlas

The same data, many angles: a growing set of information graphics over the real knowledge graph.

Deterministic and server-rendered — each figure is a pure function of the canonical graph.

World map of idea origins

Where ideas came from: each point is a concept, placed at the birthplace of the person credited (Wikidata) — a documented proxy, not an exact founding spot. Filter by discipline family.

Each point: a concept the atlas credits to a person, placed at that person’s birthplace (Wikidata) — a documented proxy for an idea’s geographic origin, not a claim of the exact spot it was founded.

Structural core (k-core)

k-core decomposition: how many concepts sit in progressively deeper shells. k=0 is isolated concepts; the deepest shell is the atlas’s densely connected backbone.

  • Core k=11,482
  • Core k=22,252
  • Core k=316

Structural roles

Every concept plays a role in the network topology — hub, cross-disciplinary bridge, connector, specialist, peripheral. Pure structure, not importance.

  • Connector1,307
  • Leaf1,272
  • Cross-disciplinary bridge1,113
  • local-hub58

Structural fragility

Articulation points (cut vertices): 874 concepts whose removal would fragment parts of the atlas. Most-connected first.

Consensus landscape

The atlas by honest epistemic status — from established to speculative. Status is authored per concept, not a derived score.

  • Established3,561
  • Strongly supported85
  • Supported56
  • Contested24
  • Uncertain14
  • Speculative10

Evidence coverage by discipline

Share of concepts per discipline backed by a Tier A/B source (primary / scholarly synthesis). Reveals where provenance is still missing — the real research backlog, not a truth measure.

Knowledge timeline

Real, sourced dates from the facts layer on one shared time axis — from antiquity (Archimedes’ principle) to 2015. Filter by discipline and era; nothing is interpolated.
