This interactive scatter plot visualizes the Iris dataset, displaying sepal length against petal length while distinguishing the three species of iris flowers through different symbol shapes. The visualization uses D3 v7 with scales and axes from the d3-scale and d3-axis modules, and encodes species using d3.scaleOrdinal with symbolsFill and symbol generators. Data is loaded from a remote CSV file, and the chart includes custom axis labels and a shape legend to identify species categories.
