This interactive dashboard displays sales data loaded from a cleaned CSV file hosted on GitHub. It provides a dataset summary, a full HTML table of all rows, and an SVG bar chart showing total sales by region. Built with D3 v7, it uses `d3.csv` and `d3.autoType` for parsing, `d3.rollup` and `d3.sum` for aggregations, and `scaleBand`/`scaleLinear` with SVG `rect` elements for the chart.
