This interactive bar chart visualizes median home prices across New York State counties from 2022 to 2024. Users can select a year via buttons, click individual bars to highlight counties, and hover to see detailed tooltips with median price and sales figures. Built with React and D3.js, the visualization uses `scaleBand` and `scaleLinear` to map county categories and price values, with `axisBottom` and `axisLeft` for chart axes. Data comes from a local CSV file containing county-level housing statistics for each year.
