This scatter plot visualizes the Iris dataset, mapping petal length to the x-axis and sepal length to the y-axis. Each flower is rendered as a circle using D3 v7’s `select`, `scaleLinear`, `csv`, and `extent` functions, with axes drawn via `axisLeft` and `axisBottom`. The SVG output fills the browser window, with data loaded from a remote CSV file and parsed into numeric fields before plotting.
