This scatter plot visualizes the classic Iris dataset, displaying sepal length against petal length for three iris species. Each species is distinguished by both color and shape: green circles for setosa, blue triangles for versicolor, and orange squares for virginica. The visualization uses D3.js v7 to load the CSV data, create linear scales for the axes, and render SVG paths with d3.axisBottom and d3.axisLeft for the chart framework.
