This scatter plot visualizes the Iris Dataset, mapping petal length and width for each flower and coloring points by species (setosa, versicolor, or virginica). The D3 v6 code loads the CSV data via `d3.csv`, uses `scaleLinear` and `extent` to set axes, and renders SVG circles with a fixed radius. It also destructures functions like `select` and axes for concise, reactive updates. The viewport fills the window, with readable 24-pixel tick labels.
