This scatter plot visualizes the relationship between flipper length and body mass for three penguin species, using a thistle background with crimson, dark blue, and green circles. Built with React and D3 v5, the code uses `d3.csv`, `d3.scaleLinear`, `d3.extent`, `d3.axisLeft`, and `d3.axisBottom` to map data from a GitHub-hosted CSV file. Each circle’s x and y positions derive from flipper and body measurements, while the `join` operator appends SVG circles with radii and species-based colors.
