This interactive scatter plot visualizes the Iris flower dataset, mapping sepal length against petal length and encoding species with distinct symbols from a shape legend. Built with D3 v7, it loads data from a remote CSV and uses modular components including `d3.scaleLinear`, `d3.scaleOrdinal`, `d3.symbol`, and custom axes and legend functions. The visualization dynamically updates to fill the viewport and recreates the plot from fetched data.
