This scatter plot visualizes the Iris Dataset, mapping petal width to sepal length for individual flowers. It uses the d3.scaleLinear and d3.scaleOrdinal APIs to position points and assign distinct symbols to each species. The d3.symbol and d3.join methods render the SVG marks, with axes generated by d3.axisLeft and d3.axisBottom. The visualization demonstrates a reusable D3 module that accepts configuration for data, dimensions, margins, and symbol size.
