This reusable scatter plot displays the Iris dataset, mapping petal width against sepal length and encoding species with distinct D3 symbol shapes. The visualization is rendered as an SVG using a custom `scatterPlot` factory function, which leverages `scaleLinear`, `scaleOrdinal`, `axisLeft`, and `axisBottom` from D3. Data is loaded asynchronously via `d3.csv` from a GitHub Gist, with numeric columns parsed on ingestion. The chart dynamically fills the browser window, showing all three Iris species with symbols differentiated by the `symbolValue` accessor.
