This interactive bar chart visualizes median home prices across New York State counties for the years 2022, 2023, and 2024. The animation demonstrates how prices shift over time, with counties sorted by median price for the selected year and interactive tooltips revealing exact median values and sales counts. Built with React and the D3.js v7 API, the visualization uses `scaleBand` and `scaleLinear` for axes, `transition()` for animated bar updates, and a button-based year selector that triggers data-driven re-rendering.
