This bubble chart displays the relationship between market capitalization and employee count for major tech companies, with bubble size encoding market cap and color distinguishing industry sectors. The visualization uses D3 v7 with SVG rendering, employing linear scales for axes, a square root scale for bubble radius, and an ordinal scale with the Set2 color scheme for industry categories. Axes are labeled “Market Cap (in millions)” and “Employees,” while a custom legend component identifies each industry. Data is loaded asynchronously from a CSV file using d3.csv and parsed with a row function.
