This scatter plot visualizes the Iris Dataset, mapping petal width against sepal length and encoding species with distinct D3 symbols. The visualization uses a reusable `scatterPlot` function that leverages `d3.scaleLinear`, `d3.scaleOrdinal`, `d3.axisLeft`, `d3.axisBottom`, and `d3.symbol` to render SVG paths. The dataset is loaded as CSV via `d3.csv` and parsed into numeric values. Axis tick labels are styled at 24px, with the plot filling the entire browser window.
