This scatter plot visualizes the Iris dataset, showing the relationship between petal length and petal width, with each point colored by species (setosa, versicolor, or virginica). The visualization uses D3 v6 with SVG rendering, employing scaleLinear, axisLeft, and axisBottom to construct the axes. Data is loaded via d3.csv from a remote GitHub URL, and circles are drawn using the select, data, and join pattern. The plot also records sepal measurements in each data point, though these are not visually encoded.
