This scatter plot visualizes the Iris dataset, displaying petal length on the x-axis and petal width on the y-axis, with each point colored by species (setosa, versicolor, virginica). Built with D3 v6 and rendered as SVG, the chart uses `d3.csv` to load data, `scaleLinear` for axes, and `axisLeft`/`axisBottom` for ticks. Circles are bound via a data join, with fill colors mapped per species, while axes labels are added as SVG text elements.
