Pick a company to see where it actually produces — every country in its footprint, shaded by capacity share — overlaid with the countries whose register actions name it (severity ring + action count), plus violet arcs to the chokepoint countries its material inputs depend on. The map is a lens; the dossier and register are the source of record.
Nippon Steel produces across 5 countries — 54% of mapped capacity sits in 🇯🇵 Japan (HQ 🇯🇵 Japan).
material exposures: silicon · manganese · chromium · nickel · vanadium · niobium · - aluminium
12 register actions name Nippon Steel, issued from 7 countries (top: 🇯🇵 Japan ×4) — 3 of those also sit in its production footprint (regulator ∩ producer).

(1 exposure without scored production data: - aluminium)Armed chokepoint: 🇨🇳 China has itself issued 3 register actions restricting the inputs it already dominates — silicon (2), manganese (1), vanadium (1) — max severity 4/5.

Named counterparties: this dossier names 1 firm with a source; 1 is in this corpus with a mapped footprint, and 1 of those produces in a country already on this map (🇧🇷 Brazil) — the named end of an exposure the country layers show anonymously.CBMM (Companhia Brasileira de Metalurgia e Mineração) (supplier, related party) 🇧🇷 BR ◆ ◆ = produces in a country already on this map.1 other dossier names Nippon Steel from the other side (supplier).
Reading the map: green shading = the company's production countries by capacity share, with dots at facility cities (dashed = approximate, country-level). Violet arcs = INPUT DEPENDENCIES — they run from the country that dominates world production/refining of a material the company consumes to the company's base; the % is that country's share of world supply at the named stage, NOT an import/export volume. Severity rings = countries whose register actions name the company.
