This interactive line chart visualizes UK unemployment rates from 1971 to 2024, with data parsed from a CSV file. Users can filter by year range using dual sliders, toggle the line visibility via a checkbox, and view statistical summaries for the selected period. The visualization uses React with D3 v7, leveraging `d3.csv` for data loading, `d3.scaleLinear` for scales, and `d3.line` for the path generation. A hover overlay with bisector-based nearest-point detection shows tooltips with exact values.
