This scatter plot visualizes the Palmer Penguins dataset, showing flipper length against body mass, with each point colored by penguin species and sized by culmen dimensions. It uses D3 v6’s `scaleLinear`, `axisLeft`, `axisBottom`, and `select` to load CSV data from a GitHub gist and render SVG circles. The axes, labels, and legend are drawn directly within the SVG canvas, and the chart is responsive to the browser window.
