This scatter plot visualizes the Iris dataset, mapping petal width and sepal length on the x- and y-axes. Each species is encoded with a distinct symbol, demonstrating a reusable D3 scatter plot component that can be re-invoked with different data, as seen when it renders a smaller test dataset. The implementation uses D3’s `scaleLinear`, `scaleOrdinal`, `symbols`, and `symbol` APIs to generate SVG paths, with axis rendering via `axisLeft` and `axisBottom`. The animation and interactive resizing are not fully implemented, but the code includes a framework for updating the chart’s width.
