This scatter plot visualizes the Iris dataset, showing the relationship between petal length and petal width, with each point colored by species (skyblue for setosa, lightgreen for versicolor, orange for virginica). The visualization uses d3.scaleLinear for both axes and d3.extent to compute the data domains. Points are rendered as SVG circles using a d3.select join operation. The chart includes axis labels and a rotated y-axis label, built with d3.axisLeft and d3.axisBottom. The data is loaded asynchronously from a CSV file using d3.csv.
