This scatter plot visualizes the Iris dataset, mapping sepal length against petal length and encoding species identity through distinct point shapes. The visualization uses D3 v7's scaleLinear, scaleOrdinal, and symbolsFill APIs to construct the axes and shape-based legend. Data is loaded from a remote CSV file via csvParse and rendered into SVG paths using the symbol generator. The example demonstrates modular code organization with local ES6 modules for axes, scatter plot, and shape legend components.
