This scatter plot visualizes the Iris dataset, showing petal length on the x-axis and petal width on the y-axis, with points colored by species (setosa, versicolor, virginica). The visualization uses d3.csv to load the data, d3.scaleLinear to map values to coordinates, and d3.axisLeft/d3.axisBottom for axes. The SVG circles are positioned using the scaled dimensions, while the code also reads sepal measurements but does not use them in the final rendering. The plot is displayed with custom font styling and colored axis labels.
