This scatter plot visualizes the Iris dataset, mapping petal length and width for each flower specimen. The D3 v6 code loads CSV data from a GitHub gist and uses scaleLinear, axisLeft, and axisBottom to construct the chart. Circles are colored by species—setosa, versicolor, and virginica—using a custom marker function, with radius fixed at five pixels. The SVG rendering includes rotated axis labels for petal length and sepal length, though the sepal label is mislabeled in the code.
