This bubble chart shows the relationship between company revenue and profit, with bubble size encoding employee count. The visualization uses D3 v7 to render SVG circles scaled against linear axes. Revenue appears on the x-axis, profit on the y-axis, and each bubble’s radius is derived from the Employees value. The chart includes axis labels and a tooltip that appears on hover, displaying company details. Data comes from an embedded CSV-like array within the script, listing 30 companies with their financial metrics. The implementation uses d3.scaleLinear for axes and bubble sizing, with d3.axisBottom and d3.axisLeft for the scales.
