This scatter plot visualizes the Iris dataset, displaying petal length and petal width for individual flowers while using color to distinguish species (setosa, versicolor, and virginica). Built with D3.js v6 as an SVG rendering, the code loads CSV data via `d3.csv`, scales values with `scaleLinear` and `extent`, and renders circles with `selectAll().join()`. The visualization includes custom axes created with `axisLeft` and `axisBottom`, labeled to show measurement dimensions.
