This scatter plot visualizes the Iris dataset, mapping petal length and width on the x- and y-axes while using circle color to distinguish the three flower species. It is rendered as an SVG using D3 version 6, with the `d3.csv` driver to load remote data and `scaleLinear`, `axisLeft`, and `axisBottom` to create the axes. Each circle’s radius is fixed, and the chart includes color-coded markers for species, making class separation immediately visible.
