This visualization displays the Iris dataset using a scatter plot, mapping petal length and width on the x and y axes while coloring each point by species (setosa, versicolor, virginica). The code loads data via `d3.csv`, scales positions with `d3.scaleLinear`, and renders circles as SVG elements with `d3.axisLeft` and `d3.axisBottom` for axes. Additional attributes for sepal dimensions are stored but not visualized. The chart uses red-labeled axes with green text and a full-screen responsive SVG canvas.
