The Challenge
The primary challenge was rendering complex real-time visualizations without performance degradation, especially when handling large datasets with thousands of data points updating simultaneously.
The Solution
We used Next.js for the frontend with React Server Components for initial data loading. D3.js was optimized with canvas rendering for large datasets, and WebSocket connections were managed efficiently with connection pooling. PostgreSQL with TimescaleDB extension handled time-series data effectively.
