This visualization presents the classic Iris dataset as a scatter plot, mapping petal length on the x-axis and petal width on the y-axis, with points colored by species (setosa, versicolor, and virginica) in skyblue, lightgreen, and orange. The code also reads sepal measurements into the data marks, though these are not directly used for positioning. Built with D3.js v6, it loads the CSV data via `d3.csv`, scales the axes with `scaleLinear`, and renders circles using SVG attributes, with `axisLeft` and `axisBottom` for labeled axes.
