This scatter plot visualizes a fork of the Penguin dataset, mapping each observation’s Perigee_km on the x-axis and Apogee_km on the y-axis, while coloring circles by species (Adelie, Gentoo, or other) and encoding bill length and depth as rectangle radii (rx, ry). The code uses d3.csv to load the data, d3.scaleLinear and d3.extent for scales, and d3.axisLeft and d3.axisBottom for axes, rendering SVG circles via a data join. Axis labels and a title are added with SVG text elements.
