Force-directed view of every material referenced in any IPTM action's target_materials field, joined to the actions that touch them and the issuer countries. Material nodes (green) are sized by action count; brighter green indicates an existing dossier in /minerals (click to navigate). Purple edges between materials are co-occurrence ties — two materials targeted by the same action — and the layout naturally clusters supply-chain stacks (battery: lithium-cobalt-nickel; CBAM: steel-aluminium-cement; CN counter-strike: gallium-germanium-rare-earths).
557 materials · 1000 actions · 113 issuers · 948 co-occurrence ties (weight ≥ 2)
5 supply-chain clusters forming in last 12m (vs prior 12m) · top pair: cobalt ↔ lithium 22→45 actions (+23)
Dissolving (3): top decline gold ↔ nickel 18→5 (-13)
Each pair = a co-occurrence in target_materials within a single action. Click any slug to filter the action register on that material. The forming list answers “where are new alliance-blocks of materials forming?”; the dissolving list flags clusters where the regulatory cadence has cooled (e.g. counter-strike waves that ran their course).
Materials most often regulated together in the same action. These pairs cluster tightly in the layout — each pair's weight is the number of actions whose target_materials lists both slugs.
