This scatter plot visualizes the Palmer Penguins dataset, showing flipper length on the x-axis against body mass on the y-axis, with each point colored by species (Adelie in green, Gentoo in violet, and Chinstrap in red). The visualization uses D3 v5 within a React framework, rendering circles via SVG. The code leverages `d3.csv` for data loading, `scaleLinear` for axes, and `extent` to compute domains, while also encoding bill length and depth as unused circle radius properties.
