This scatterplot visualizes the Penguin Dataset, plotting flipper length on the x-axis and body mass on the y-axis, with each circle colored by penguin species. The code uses D3 v7’s `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to load data, map scales, and render axes. SVG circles are positioned using the linear scales, with fill colors assigned per species via a custom marker function, and includes axis labels and a title.
