This interactive scatter plot visualizes the Iris dataset, mapping petal width and sepal length along the x and y axes while using distinct symbols to represent different species. Built with D3 v6 and React, it renders as an SVG that fills the browser window. The reusable `scatterPlot` component leverages `scaleLinear`, `scaleOrdinal`, `symbols`, and `symbol` to generate the plot, with `axisLeft` and `axisBottom` for the axes. The chart also provides the 100-pixel marks and axis tick styling via CSS.
