This example displays a scatter plot of country-level data from the world-data-2023.csv file, plotting life expectancy on the x-axis and birth rate on the y-axis. The visualization uses D3 v6’s `csv`, `scaleLinear`, `axisLeft`, and `axisBottom` APIs to parse the data, map the scales, and render SVG circles with color-coded markers. Despite a title referencing penguin species, the code actually maps each circle’s color based on a species field, while axis labels incorrectly reference flipper length and body mass, reflecting a mismatch between the intended and actual data display.
