Architecture

The frontend is a React application with TypeScript for type safety. D3.js and Chart.js power the visualizations with custom hooks for data fetching and caching. The REST API aggregates data from multiple sources, with WebSocket connections for live updates.

How It Works

Data is fetched from backend APIs and cached using SWR for optimal performance. Users can customize their dashboard by adding, removing, and rearranging widgets. Charts update in real-time via WebSocket connections. Users can filter data by date range, categories, and custom dimensions. Export functionality generates CSV or PDF reports from current view data.
