This scatter plot visualizes the Iris dataset, encoding petal length on the x-axis, petal width on the y-axis, and species via point color (skyblue, lightgreen, and blue). It uses D3 v6 with `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to load data, map scales, and render SVG circles and axes. The code parses numeric measurements from the CSV and applies a custom color function per species, with axis labels styled in green.
