This interactive scatter plot visualizes the Iris dataset, showing the relationship between petal length and petal width. The plot uses D3 v6 with a linear scale for both axes, rendering data points as steelblue circles in an SVG. The code fetches CSV data from a GitHub gist, parses the numeric measurements, and uses `d3.scaleLinear`, `d3.extent`, `d3.axisBottom`, and `d3.axisLeft` to construct the chart. Axis lines and ticks are partially removed for a cleaner appearance, and labels for both axes are added.
