This visualization displays the Iris dataset using a scatter plot, with petal length plotted on the x-axis and petal width on the y-axis, while points are color-coded by species (setosa, versicolor, and virginica). The chart uses D3.js v6, with `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` defining the scales and axes. Data is loaded via `d3.csv` from a GitHub gist, and each data point is rendered as an SVG circle with attributes set through D3’s data join.
