This D3.js (v6) scatterplot visualizes the Iris dataset, plotting petal length against petal width on the x- and y-axes while encoding species with colored circles (skyblue, lightgreen, and orange). The chart displays labeled axes and a title, with points rendered as SVG circles and scaled using linear scales derived from the data extent. It loads the CSV from a GitHub Gist, parses numeric fields, and uses D3's `scaleLinear`, `axisLeft`, and `axisBottom` APIs. The visualization includes a rotated y-axis label and a bottom axis label, though the code references undefined `innerHeight`/`innerWidth` variables.
