This scatter plot visualizes the Iris Dataset, mapping sepal length against petal width with D3 v6. The code uses `d3.csv` to load data and `d3.scaleLinear`, `d3.axisLeft`, and `d3.axisBottom` for scales and axes. A `d3.scaleOrdinal` and `d3.symbol` generator draw points as SVG paths, with symbol types based on species. The `scatterPlot()` function is reusable, configured via chained methods for dimensions, margins, and accessors.
