This bubble chart visualizes supermarket sales data, plotting sales against discount values for individual orders. The x-axis represents discount percentages (capped at 500), while the y-axis shows sales figures. Bubble radius encodes the profit margin, and color distinguishes product categories (Furniture, Office Supplies, Technology), with accompanying legends for size and category. Built with d3.v7, the SVG visualization uses `d3.csv` to load data, `d3.scaleLinear` for axes, `d3.scaleOrdinal` for color mapping, and `d3.schemeSet1` for the palette.
