This example uses D3 v6 to create an interactive scatter plot from the Iris dataset, loading CSV data via `d3.csv` and rendering SVG circles for each observation. It maps petal length and width to the x and y axes using `d3.scaleLinear`, with colors distinguishing the three iris species (setosa, versicolor, and virginica). The axes are generated with `d3.axisLeft` and `d3.axisBottom`, and axis labels identify the variables. The chart fills the browser window and includes a legend via the species colors, demonstrating a straightforward data-driven visualization workflow.
