This bubble chart visualizes sales performance for 39 products, plotting Revenue on the x-axis against Units Sold on the y-axis, with bubble radius encoding units sold and color encoding product category (Electronics, Apparel, Home Decor). Hovering over a bubble reveals a tooltip with product details. Built with D3 v7, it uses d3.scaleLinear for axes, d3.scaleSqrt for bubble sizing, and d3.scaleOrdinal with d3.schemeCategory10 for category colors, rendering SVG elements from a CSV data source.
