This scatter plot visualizes the Iris dataset, showing the relationship between petal length and petal width, with each point colored by species. The code uses d3.csv to load the data, d3.scaleLinear to map the coordinates, and d3.axisLeft and d3.axisBottom for the chart axes. Circles are drawn in SVG, with colors assigned to setosa, versicolor, and virginica. Extra attributes for sepal dimensions are also bound to each circle, though only petal dimensions determine their position.
