This scatter plot visualizes the Palmer Penguins dataset, mapping flipper length on the x-axis and body mass on the y-axis. Each circle is colored by penguin species—blue for Adelie, green for Gentoo, and red for Chinstrap—allowing quick comparison of morphological traits across groups. The D3 code loads the data via `csv()`, uses `scaleLinear()` for axis scaling, and renders circles with SVG, while `axisBottom()` and `axisLeft()` add labeled axes.
