This scatterplot maps each country’s birth rate against its calling code, with circle radius scaled by infant mortality, using data from the world-data-2023.csv dataset. The code employs d3.scaleLinear for both axes and d3.axisBottom/axisLeft to render ticks, while d3.csv fetches the remote data. Circles are drawn with SVG via d3.select and .join, and mouseenter events log the underlying data points. The visualization reveals an unorthodox pairing of unrelated numeric attributes, producing a largely arbitrary distribution across the 900×400 pixel SVG canvas.
