This scatter plot visualizes the Iris Dataset, mapping petal width and sepal length for individual flowers while encoding species with different D3 symbols. The reusable `scatterPlot` function uses `d3.scaleLinear` for both axes, `d3.scaleOrdinal` to assign symbols from the `d3.symbols` collection, and `d3.symbol().size()` to generate paths. Data is loaded via `d3.csv`, and the plot renders in SVG with axes created by `d3.axisLeft` and `d3.axisBottom`.
