A scatter plot visualizes penguin measurements, plotting flipper length on the x-axis against body mass on the y-axis, with each point colored by species. The code uses D3 v7’s `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to load and render the data as SVG circles. Culmen length and depth are also parsed but not visualized. Axis labels and a title are added via SVG text elements, with the plot sized to the full browser window.
