br/acc (World Transparency Graph) is an open-source project by Brazilian developer Bruno Clz that addresses a fundamental problem in civic accountability: government data is technically "open" but so fragmented across dozens of separate portals that it is practically inaccessible.

The project ingests 45+ official Brazilian public datasets — company registries, health records, education metrics, procurement data, and more — and connects them through a Neo4j graph database, exposing a unified API and a React-based search interface for exploration.

## Why it matters

The accountability problem br/acc addresses is universal: governments publish data, but citizens and journalists rarely have the technical capacity to join it across sources. Fragmentation functions as a de facto accountability sink — data is available in principle but inaccessible in practice. br/acc is a working demonstration of how civic tech can bridge that gap.

With 1.7k GitHub stars and 463 forks, it has significant traction in the Brazilian civic tech community and serves as a model for similar efforts in other jurisdictions.
