This scatter plot visualizes the Iris dataset, showing the relationship between petal length and petal width across three iris species, with each species represented by a distinct color. The visualization uses D3 v6 to load the CSV data, create linear scales with d3.scaleLinear, and render SVG circles. Axes are generated using d3.axisLeft and d3.axisBottom, with axis labels for both variables. The code also parses additional sepal measurements but uses them only as data attributes rather than for visual encoding.
