This scatter plot visualizes the Iris dataset, mapping petal width on the x-axis against sepal length on the y-axis. It uses distinct symbols for each iris species, generated via D3's `scaleOrdinal` and `symbol` APIs to differentiate categories. The plot is rendered as an SVG, with axes created using `axisLeft` and `axisBottom`. The reusable chart component, inspired by Bostock’s "Towards Reusable Charts," accepts configurable data, value accessors, margins, and symbol size, demonstrating a modular approach to D3 visualization.
