This visualization explores Amazon sales data through an interactive dashboard built with D3.js. It begins with a summary section displaying key metrics like total sales, order count, and top product. The analysis presents a bar chart of sales by category using `d3.scaleLinear` and `d3.scaleBand`, alongside a line chart tracking sales over time with `d3.scaleTime` and `d3.curveMonotoneX`. All charts are rendered as SVG elements, with data loaded from an external CSV file via the `fetch` API and parsed using `d3.csvParse` and `d3.autoType`.
