This bubble chart shows how major technology companies compare across three financial and operational metrics: annual revenue, profit margin, and employee count. Each company appears as a circle positioned by its revenue on the x-axis and profit margin on the y-axis, with the bubble’s size encoding employee numbers and colors distinguishing companies. The visualization uses D3.js v7 with SVG rendering, employing `d3.scaleLinear` for the axes, `d3.scaleSqrt` for bubble sizing, and `d3.scaleOrdinal` with `d3.schemeCategory10` for colors. Interactive tooltips appear on mouseover, and the chart reads data from a CSV file containing the ten companies’ figures.
