This scatter plot visualizes the Palmer Penguins dataset, showing the relationship between culmen length and culmen depth, with each species—Adelie, Gentoo, and Chinstrap—represented by a distinct color (blue, green, and red). The code uses d3.csv to load data from a GitHub URL, d3.scaleLinear to map data to screen coordinates, and d3.axisLeft and d3.axisBottom to render axes. SVG circles are drawn using a data join, and axis labels are added via d3.select, with the chart sized to the full browser window.
