Show HN: I mapped the latest UK fuel prices by county

This project leverages publicly available government data to create a valuable consumer utility: a real-time map of UK fuel prices. The aggregation by county, coupled with filters and detailed metrics (cheapest forecourt, average, spread), directly addresses a consumer pain point of price opacity and the desire for cost savings. From a B2B perspective, this demonstrates the power of data aggregation and visualization for market intelligence. Similar approaches could be applied to other public datasets (e.g., energy prices, commodity costs) to provide competitive insights for businesses. The reliability of the official feed and frequent updates (every 30 minutes) are critical for maintaining data accuracy and user trust, highlighting the importance of robust data pipelines in any data-driven service.
