This scatter plot visualizes the Iris dataset by mapping petal length and petal width on the x- and y-axes, with each point colored by species (setosa, versicolor, or virginica) using orange, skyblue, and lightgreen fills. Built with D3 v6, it renders as an SVG and loads data via `d3.csv`, scales axes with `d3.scaleLinear`, and draws circles with `selectAll('circle')` and a `.join('circle')` operation. Axis labels use green text, and the plot adapts to the browser window’s dimensions.
