A scatter plot displays the relationship between petal length and sepal width in the Iris Dataset, with each point representing a flower sample. The visualization uses React to render SVG elements, with D3 v5 functions like `scaleLinear`, `extent`, and `format` handling scales and tick label formatting. Axes are built as reusable React components that map data values to screen coordinates, while circles with tooltip titles show the data points against a muted color palette.
