Corpus map
2939 compounds projected from their record text into two dimensions (PACMAP over BAAI/bge-large-en-v1.5).
Proximity means described similarly — same class, structural family, mechanism and asserted roles — not structurally similar. These are text embeddings of what the corpus says about a compound; SMILES and InChI are deliberately excluded, because a sentence model reads them as noise. A chemical-similarity map is a different artifact.
The scatter is a visual aid, and mouse-driven: its points are canvas pixels, not focusable links, so it is not navigable by keyboard or screen reader. Nothing is only available here — every compound has a record page reachable from Browse, and the per-class pages list the same records in text. Said plainly rather than implied, because a scatter that is the sole route to some records would be an accessibility failure rather than a limitation.
