This scatter plot visualizes the Iris dataset, mapping petal length and width for individual flowers while encoding species with distinct colors. The visualization uses D3 v6, loading data from a CSV file and rendering circles as SVG marks. It demonstrates D3's scaleLinear, extent, axisLeft, and axisBottom APIs to construct the chart, with a custom marker function assigning skyblue, lightgreen, or orange based on species. The plot includes rotated axis labels and uses window dimensions for responsive sizing.
