This scatter plot visualizes the Iris dataset, showing the relationship between petal width and sepal length for three species. The plot encodes species identity through distinct D3 symbols, including a custom square symbol, and uses D3’s `scaleLinear` for axes and `scaleOrdinal` for symbol mapping. Data is loaded via `d3.csv` and rendered as SVG paths, with axes generated using `axisLeft` and `axisBottom`.
