E-Commerce Dashboard
A real-time analytics dashboard for e-commerce stores with interactive charts, inventory tracking, and sales forecasting built with Next.js and D3.js.
Overview
A comprehensive analytics dashboard designed for e-commerce store owners who need real-time visibility into their business metrics. The dashboard aggregates data from multiple sources and presents it through interactive visualizations.
Problem
E-commerce store owners often struggle to get a unified view of their business performance. Data is scattered across payment processors, inventory systems, and marketing platforms, making it difficult to make informed decisions quickly.
Solution
Built a centralized dashboard that connects to multiple data sources via REST APIs, processes the data in real-time, and presents it through interactive D3.js visualizations. The dashboard includes customizable widgets, date range filters, and export functionality.

Lessons Learned
Working with D3.js inside React required careful management of the DOM to avoid conflicts between React's virtual DOM and D3's direct DOM manipulation. Using refs and useEffect hooks provided a clean integration pattern.
