This dashboard presents four synchronized views of sales data: a bar chart, a U.S. choropleth map, a scatter plot, and a pie chart. It uses several D3.js v6 APIs, including `scaleBand`, `scaleLinear`, `geoAlbersUsa`, `geoPath`, `pie`, and `arc`. The map colors states based on total sales from the provided dataset, while the pie chart breaks down sales by sub-category. All visualizations support interactive tooltips and updates with animation.
