This reusable scatter plot visualizes the Iris dataset, mapping petal width against sepal length and encoding species with distinct D3 symbol shapes (circles, crosses, and diamonds). Built with the reusable chart pattern, the `scatterPlot()` function configures scales, axes, and symbol generators via chained accessor methods. The visualization renders as animated SVG, with axes created using `axisLeft` and `axisBottom`, while `scaleOrdinal` and `symbol` map categorical data to geometric marks. Data loads asynchronously via `d3.csv` and updates smoothly through D3’s data join.
