This visualization displays the Iris dataset as a scatter plot, plotting petal length on the x-axis against sepal length on the y-axis. Each data point is rendered as a circle using D3 v6’s selection and join methods, with scales defined by `scaleLinear` and axes generated via `axisLeft` and `axisBottom`. The plot fills the entire browser window, and the code loads CSV data asynchronously with `d3.csv`, parsing numeric fields before mapping coordinates to SVG circles.
