# Public Money Graph

Public Money Graph is an interactive temporal network of observed French public
procurement: which public buyers contract with which companies, in which
sectors, and what source evidence supports every relationship.

## Data

- Source: DECP award-notice records (Données essentielles de la commande
  publique), published on data.gouv.fr under the Etalab Open Licence.
- Legal-unit identities resolved against SIRENE.
- Amounts are declared contractual values of awarded contracts, not treasury
  payments. A large or repeated relationship is a structural observation,
  never an allegation.
