This scatter plot visualizes penguin measurements, with flipper length on the x-axis, body mass on the y-axis, and each point colored by species (orange for Adélie, red for Chinstrap, green for Gentoo). Using D3 v5 and React, the code loads a CSV dataset via `d3.csv`, parses numeric columns, and renders circles with `d3.scaleLinear` for axes and `d3.axisLeft`/`d3.axisBottom` for tick marks. The SVG is sized to the window, and point radius is fixed while culmen dimensions are stored but not visually mapped.
