This example visualizes the Iris dataset as a scatter plot, mapping petal width and sepal length to the x and y axes. Each of the three iris species is represented by a distinct symbol from D3’s `symbol` and `symbols` APIs, with positions scaled using `scaleLinear` and axes drawn via `axisLeft` and `axisBottom`. The chart is built with a reusable `scatterPlot` function in D3 v6, rendering SVG shapes whose paths are generated by `symbolGenerator`, and loaded asynchronously from a CSV URL.
