This scatter plot visualizes the Iris dataset, showing petal length against petal width for three species, each represented by a distinct color (skyblue for setosa, lightgreen for versicolor, orange for virginica). Built with D3 v6, the visualization uses `d3.select`, `d3.csv`, `d3.scaleLinear`, `d3.extent`, `d3.axisLeft`, and `d3.axisBottom` to load data from a remote CSV, map the quantitative fields, and render SVG circles with fixed radius. The chart includes rotated and bottom axis labels, with styling applied through CSS. The code reads petal and sepal measurements directly from the parsed rows, though only the petal dimensions are plotted.
