A scatter plot of the Iris dataset displays petal length against sepal width, with each of the 150 flowers represented as a circular mark. The visualization is built with React and D3 v5, using `scaleLinear` for both axes and `extent` to compute domains from the loaded CSV data. Axis ticks are generated via `xScale.ticks()`, with labels formatted using D3's `format` utility. The SVG rendering applies a Poppins font and custom styling for ticks and marks, while hover tooltips expose exact petal length values through SVG `<title>` elements.
