This scatter plot visualizes the Iris dataset, showing petal length against petal width, with points colored by species: setosa, versicolor, and virginica. The visualization uses D3 v6 to load CSV data and render circles on an SVG canvas, with axis labels for petal length and sepal length. Axes are generated using `d3.axisLeft` and `d3.axisBottom`, while the data is scaled with `d3.scaleLinear` and `d3.extent`. The plot is built entirely with D3 selections, appending circles and text elements directly to the SVG.
