This interactive scatter plot visualizes the Iris dataset, comparing sepal length against petal width. Each flower species is represented by a distinct D3 symbol, generated using `scaleOrdinal` and the `symbol` API, with axes rendered via `axisLeft` and `axisBottom`. The reusable chart pattern, defined in `scatterPlot.js`, is invoked with D3’s selection `.call()` method, and the SVG output resizes to the full window. The data is loaded asynchronously from a CSV URL using `d3.csv` and parsed into numeric fields before plotting.
