This dashboard displays sales data from the Superstore dataset across four synchronized views: a pie chart of sub-category sales, a bar chart for category totals, a scatter plot of individual orders by date and sales amount, and a geographic map of US regions. The visualization uses D3 v6 with `d3.pie`, `d3.arc`, `d3.scaleBand`, `d3.scaleTime`, and `d3.geoAlbersUsa` for the map projection. Data is loaded from a CSV file, and interactive tooltips appear on hover. SVG rendering with transitions updates the charts when data changes, while Moment.js parses date strings for the time axis.
