A scatter plot displays the Iris dataset, mapping petal length on the x-axis and petal width on the y-axis, with points colored by species (setosa, versicolor, virginica) using skyblue, lightgreen, and orange. Circles also store sepal length and width as properties, though these are not visually encoded. The visualization loads data from a GitHub CSV using `d3.csv`, scales with `scaleLinear` and `extent`, and renders as SVG circles via `selectAll` and `join`. Axes are generated with `axisLeft` and `axisBottom`, with custom labels added as SVG text.
