A scatter plot visualizes the Iris Dataset, mapping petal length on the x-axis against sepal width on the y-axis. It uses React and D3 v5 to build an SVG chart with a linear scale for both dimensions, styled with teal circles and gray tick marks. The data is loaded asynchronously via `d3.csv` and rendered with custom Axis components, a `Marks` component using SVG circles, and formatted tick labels using `d3.format`.
