This bubble chart plots ten major technology companies by revenue on the x-axis and profit on the y-axis, with each circle’s radius scaled to revenue and color encoding geographic region. The chart uses d3.scaleLinear for both axes, d3.scaleSqrt for bubble size, and d3.scaleOrdinal with d3.schemeCategory10 for region colors. Hover tooltips appear via appended SVG <title> elements, while axis labels are positioned manually with SVG text elements. The static synthetic dataset is hardcoded in the D3 v7 script.
