This scatter plot visualizes the Iris dataset, showing the relationship between sepal length and petal length for three iris species. The plot encodes species identity through different symbol shapes: circles for Iris-setosa, squares for Iris-versicolor, and triangles for Iris-virginica, with a legend displayed in the upper-right corner. The visualization is built using D3 v7, with axes rendered via d3.axisBottom and d3.axisLeft, points drawn as SVG paths using d3.symbol, and data loaded from a CSV URL using d3.csv.
