This scatter plot visualizes the Iris dataset, mapping petal width against sepal length and encoding species with distinct D3 symbol shapes. Using d3.csv to load data and d3.scaleLinear for axes, the code applies a reusable factory pattern via `scatterPlot()`, with d3.scaleOrdinal and d3.symbol to generate marks. SVG rendering includes labeled axes and a title, while the plot adapts to the full browser window size with margins defined in the configuration.
