This scatter plot visualizes penguin measurements, with flipper length on the x-axis and body mass on the y-axis, colored by species (Adelie, Gentoo, and Chinstrap) using red, blue, and black. It loads data from a CSV via `d3.csv`, parses numeric fields, and renders circles with `d3.scaleLinear` and `d3.axisLeft`/`d3.axisBottom` in SVG. The chart also encodes bill length and depth through circle `rx` and `ry` attributes, though these are minimally visible at the fixed radius of 5 pixels.
