A scatter plot of the Iris Dataset shows petal length on the x-axis and sepal width on the y-axis, with semi-transparent circular marks. Built with React and D3 v5, it uses `scaleLinear` with `.nice()` for continuous scales, custom `AxisBottom` and `AxisLeft` components for tick rendering, and a `Marks` component that maps data to SVG circles with native `<title>` tooltips. The visualization loads CSV data via D3's `csv` function and displays axis labels for both dimensions.
