This scatter plot visualizes Palmer Penguins data, mapping flipper length on the x-axis and body mass on the y-axis, with each point colored by species (Adelie, Gentoo, or Chinstrap). The SVG rendering uses D3 v5’s `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to position points and draw axes. Circle radius is fixed, while bill length and depth values are set as unused `rx` and `ry` attributes. The code loads CSV data via `d3.csv`, parses numeric fields, and appends axes and labels directly within a React-based HTML page.
