Vibe Coding #5 - Data Analytics Dashboard with Svelte & Python | ENTSO-E API Energy Data

Description

📄 More resources: https://datons.com/go/e4wbs6 Hover over Germany and watch prices update. Click France and compare generation mix side by side. Drag a time range and see cross-border flows recalculate — all in real time, across 45+ European bidding zones. We build an interactive energy dashboard from scratch with Svelte and D3.js, powered by a FastAPI backend and our open-source python-entsoe library. Every interaction triggers dynamic calculations — no page reloads, no static charts. What we build: • Interactive SVG map of Europe with 45+ ENTSO-E bidding zones • Dynamic hover tooltips with live price and generation data • Generation mix breakdown (solar, wind, nuclear, gas, hydro) per zone • Cross-border electricity flow visualization between countries • Day-ahead price curves with hourly granularity and multi-zone comparison • FastAPI backend serving live data from ENTSO-E Transparency Platform 🔧 Tools used: • Claude Code (Anthropic) • Svelte + D3.js • FastAPI + python-entsoe • ENTSO-E Transparency Platform • uv (package management) 💬 Custom AI solutions?: https://datons.com/go/discover 📬 Newsletter: https://datons.com/go/newsletter #VibeCoding #Svelte #EnergyDashboard #ENTSOE #Python #DataViz #OpenSource #BiddingZones #InteractiveDashboard
