This visualization displays the Iris dataset as a scatter plot. It shows the relationship between petal width and sepal length, with each of the three iris species represented by a distinct color and symbol. The plot uses D3's `scaleLinear`, `scaleOrdinal`, `symbol`, `axisLeft`, and `axisBottom` functions to map data values to visual properties. The `scatterPlot` function is a reusable component, configured via a fluid interface, and renders as an SVG.
