A bar chart shows median home prices for sixteen U.S. cities, sorted from highest to lowest value. Clicking a bar reveals a details panel with population, rent, income, job growth, and unemployment data for that city. Built with React and D3 v7, it uses `scaleBand` and `scaleLinear` for axes, a ResizeObserver for responsive sizing, and D3's enter-update-exit pattern to animate bars and the details panel. Data loads asynchronously from a CSV file via `d3.csv`.
