This example shows a scatter plot of penguin measurements, comparing flipper length on the x-axis against bill depth on the y-axis. Each point represents an individual penguin, colored by species (Adelie, Gentoo, Chinstrap) via a d3.scaleOrdinal mapping to red, green, and blue. The visualization loads data from a CSV file using d3.csv, applies linear scales (d3.scaleLinear) for both axes, and renders circles within an SVG element. Axis labels and rotated tick text are added using d3.axisBottom and d3.axisLeft.
