This scatter plot visualizes the Iris dataset, showing petal length on the x-axis and petal width on the y-axis, with each point colored by species (setosa, versicolor, or virginica) using SVG circles. The code loads data from a GitHub-hosted CSV, parses numeric fields, and uses D3 v6 scales such as `scaleLinear` and functions like `extent`, `axisLeft`, and `axisBottom` to render axes and labels. Circle radii are fixed, while the `rx` and `ry` attributes are set from sepal measurements, though these do not visually alter the circles’ appearance. The visualization fills the browser window and includes custom axis labels.
