Analytics Dashboard Stack (React, D3, Recharts, Python, FastAPI, Grafana) overview

A data analytics dashboard combining React with D3 and Recharts for rich, interactive visualizations — from time-series charts and heatmaps to custom SVG-based diagrams. Python with FastAPI serves as the analytics API layer, running complex aggregation queries and statistical computations. Pandas and NumPy handle server-side data processing. Grafana provides complementary operational dashboards for monitoring data pipeline health. PostgreSQL or a columnar store holds the aggregated analytics data. The tradeoff is a split-language stack — TypeScript on the frontend, Python on the backend — which requires careful API contract management and two separate build pipelines, but unlocks Python's superior data science ecosystem on the server side.
