This visualization is a scatter plot of Palmer Penguin data, showing the relationship between flipper length (x-axis) and body mass (y-axis). Each circle represents a penguin, colored by species: Adelie (yellow), Gentoo (green), and Chinstrap (blue), while the circle’s rx and ry attributes are set to the bill length and depth values, though the visual effect is subtle. Built with D3 v5, the code loads a CSV via `d3.csv`, uses `scaleLinear` for axes, and draws SVG circles with `selectAll` and `join`. Axis labels and a title are added as SVG text elements.
