This scatter plot visualizes the Iris Dataset, displaying petal length against petal width for individual flowers. Each point is colored by species, using blue, red, and black to distinguish setosa, versicolor, and virginica. The visualization uses D3 v6 APIs including `select`, `scaleLinear`, `extent`, and `axisBottom` to map data to SVG circles, with point radius fixed while sepal dimensions are encoded as rx and ry attributes on the circle elements. The chart fills the entire browser window.
