This interactive scatter plot visualizes the classic Iris dataset, using D3.js v7 to map sepal length against petal length. Points are encoded with both color and shape to distinguish the three iris species (Setosa, Versicolor, and Virginica), with a legend showing the shape-to-species mapping. The visualization pulls data from a remote CSV file, parses it, and uses D3 scales for linear axes. The rendering uses D3 modules for scatterplot creation and shape-based legends, with circles, triangles, and squares representing each species.
