This bubble chart displays the relationship between pharmaceutical R&D spending, the number of approved drugs, and revenue. Each bubble represents a company, with its x-position mapped to approved drugs and y-position to R&D spending, while the bubble’s radius encodes revenue in billions. The visualization uses D3 v7’s scaleLinear for axes and bubble sizing, d3.axisBottom and d3.axisLeft for the chart’s scales, and d3.interpolateTurbo to color each bubble. Data is loaded from a CSV file, and labels annotate each bubble with the company name. A legend clarifies the revenue scale.
