This scatter plot displays the penguin dataset, mapping flipper length and body mass with colored circles that represent species (yellow for Adelie, green for Gentoo, brown for Chinstrap). It also encodes bill length and bill depth as circle radii, adding a second dimension of comparison. Built with React and d3.v5, the example loads CSV data via `csv`, scales with `scaleLinear`, and renders SVG circles with axes from `axisLeft` and `axisBottom`. Axis labels and a title are added manually, with styling applied through CSS.
