This example shows a scatter plot of the Iris dataset, visualizing petal length versus sepal length with tooltips revealing exact coordinates on hover. The visualization is rendered as an SVG using D3 v6, with circles positioned using linear scales computed from the data’s extent. The code explicitly references the CSV via a GitHub gist URL, parses numeric columns, and employs `axisLeft` and `axisBottom` for labeled axes. The chart adapts to the browser viewport dimensions, and each data point includes a title element for interactive details.
