This scatter plot visualizes the Iris dataset, mapping petal length and petal width to x and y axes while coloring each point by species (setosa, versicolor, or virginica). The visualization uses D3 v6’s `scaleLinear`, `extent`, `axisBottom`, and `axisLeft` to construct the chart, with circles rendered as SVG elements. Data is loaded via `d3.csv` from a GitHub gist, and radii are set to a constant value despite additional sepal measurements being parsed. Axis labels appear rotated for the y-axis, and the full window dimensions define the SVG canvas.
