This interactive scatter plot visualizes the Iris dataset, mapping petal length against sepal width for each flower specimen. The visualization uses d3.scaleLinear to compute x- and y-axis scales from the data extent, with React functional components rendering SVG marks and axes. Hovering over a circle reveals a tooltip displaying the petal length value via the native SVG <title> element. The chart fetches CSV data from a GitHub gist using d3.csv and applies tick formatting with d3.format, styled with Poppins typography and a teal color scheme.
