This scatter plot shows the relationship between sales amount and number of orders, with each point colored by product category (electronics, cosmetics, or clothing). The visualization loads CSV data from a GitHub gist, uses `d3.csv` to parse the dataset, and renders circles via SVG. It employs `d3.scaleLinear` for both axes, `d3.axisBottom` and `d3.axisLeft` for ticks, and a `d3.scaleOrdinal` to map categories to colors. A manually positioned legend explains the color coding at the bottom-right corner.
