This example visualizes the Palmer Penguins dataset as a scatter plot, mapping flipper length on the x-axis and body mass on the y-axis. Each circle is colored by penguin species (yellow for Adelie, green for Gentoo, brown for Chinstrap) and encoded with bill length and depth as elliptical radii. Built with React and D3 v5, it uses `csv()` to load remote data, `scaleLinear` for axes, and `axisLeft`/`axisBottom` for ticks. The SVG is rendered full-screen, with custom font styling and axis labels displayed prominently.
