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.
Sigma Lithium Corporation produces across 1 country — 100% of mapped capacity sits in 🇧🇷 Brazil (HQ 🇧🇷 Brazil).

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.
