This animated bar chart displays the top six most visited U.S. National Parks as of 2022, ranking them by visitor count using interactive bars. Built with D3.js, it uses `scaleBand` and `scaleLinear` for positioning, with axes rendered via helper functions. The visualization responds to mouse movement by tracking `hoveredX` and `hoveredY` coordinates, triggering tooltips that show each park’s name and visitor totals. Data comes from the `@vspatel987/national-park-2022` package, and the chart animates through a resize observer, updating the SVG dimensions dynamically.
