This scatter plot visualizes the Iris dataset, showing petal length against petal width, with each circle colored by species (skyblue for setosa, lightgreen for versicolor, orange for virginica). The D3 v6 code loads CSV data from a GitHub repository, uses scaleLinear and extent to establish scales, and renders circles as SVG marks with attributes for position and fill. Axis labels appear for both dimensions, and the chart fills the entire window.
