This interactive scatter plot visualizes the Iris Dataset, displaying petal length and width for individual flowers while also encoding sepal length and width as point size parameters. Three iris species—setosa, versicolor, and virginica—are distinguished by orange, black, and red fills. Built with D3 v6, the visualization uses `d3.csv` to load data, `d3.scaleLinear` for coordinate mapping, and `d3.axisLeft` and `d3.axisBottom` for chart axes. The plot is rendered as an SVG with circles and labeled axes, with data fetched from a remote CSV source.
