This scatter plot visualizes the Penguin Data Set, mapping flipper length to body mass for individual penguins. Each point’s color encodes the penguin species—Adelie, Gentoo, or Chinstrap—using a manual color scale. The axes are labeled to indicate the measured variables. Built with D3 v5 and React, the visualization uses `d3.csv` to load the data and `d3.scaleLinear` to project values. It renders circles as SVG marks, while `axisLeft` and `axisBottom` generate the corresponding axis ticks.
