This interactive bar chart displays median home prices across New York State counties for 2022, 2023, and 2024, with counties sorted by price for the selected year. Users can switch years via buttons or click bars to highlight specific counties. A hover tooltip reveals a mini line chart showing that county’s price trend across all three years. Built with React and D3 v7, it uses `scaleBand`, `scaleLinear`, `axisBottom`, `axisLeft`, and `transition` for animated bar updates, with data loaded from a CSV file.
