// the problem

Challenge

Visualizing complex relationships between entities (people, companies, events) requires intuitive graph rendering while maintaining performance with large datasets. Building an AI research agent that can autonomously discover connections adds another layer of complexity.

// what we built

Solution

Juba uses interactive force-directed graph visualization for network mapping. The Research Agent leverages leading AI models with tool calling to autonomously discover entity connections. Multi-layer security with session fingerprinting and encryption protects sensitive investigations. The crime board aesthetic provides unique usability.
