This scatter plot visualizes the relationship between flipper length and body mass for three penguin species, with each point colored by species. Built with D3 v5 and React, it renders an SVG graphic with axes labeled and a title. The code uses `d3.csv` to load data, `d3.scaleLinear`, `d3.extent`, and `d3.axisLeft`/`d3.axisBottom` for scaling and axes, and manually maps species to colors.
