This scatter plot visualizes the Iris Dataset, mapping petal length on the x-axis and sepal length on the y-axis. It uses D3 v6’s `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to load data, compute scales, and render axes. Circles are drawn with SVG via `selectAll` and `join`, with coordinates transformed from data values to pixel positions. The plot fills the browser window and includes a 24-pixel tick font for readability. Data is fetched from a GitHub Gist, and parsing converts numeric fields with `+d`.
