This example visualizes the Iris Dataset, plotting petal length against petal width for three iris species, each colored blue, red, or black. It uses D3 v6 with `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to load data, scale axes, and render an SVG scatter plot. Circles are positioned on the x- and y-scales, with the underlying sepal measurements stored as `rx` and `ry` attributes. The visualization fills the browser window and includes labeled tick marks with enlarged font sizes.
