This interactive pie chart visualizes the proportion of unemployment across up to 30 U.S. states, with each slice sized by the state’s total unemployment percentage. Hovering a slice expands it and shows a tooltip with the state name, value, and percentage, while clicking a slice displays the selected state below the chart. A legend filters data by region on click and highlights matching slices on hover. Built with D3.js, it uses `pie`, `arc`, `scaleOrdinal`, and `transition.attrTween`-style animations, pulling data from the `@oabouhas/unemployment` package.
