This scatter plot visualizes penguin measurements from a CSV dataset, mapping flipper length to body mass for each individual. Three species—Adelie, Gentoo, and Chinstrap—appear as yellow, green, and brown circles, respectively. The code loads data via `d3.csv`, uses `d3.scaleLinear` for axes, and renders SVG circles using `select` and `join`. Axis labels and a title are added with `axisLeft`, `axisBottom`, and SVG `text` elements.
