This interactive pie chart displays fruit counts across five regions—East, West, North, South, and Central—loaded from a TSV file. Built with React and D3 v5, it uses `d3.pie`, `d3.arc`, and `d3.nest` to aggregate data, with SVG paths and labels animated via `transition.attrTween`. A radio-button option component, rendered with D3 selections, lets viewers switch between fruit categories, redrawing the chart with a Tableau10 color scale.
