This scatterplot visualizes the Iris dataset, plotting petal length against sepal width for individual flowers, with hover tooltips revealing exact measurements. The chart uses React with D3 v7, employing `scaleLinear` for axes and `extent` for domain calculation, while SVG circles render the data points. Axis components generate ticks and labels through D3's `ticks()` method. The visualization uses `d3.csv` to fetch and parse the dataset, with marks styled using CSS classes and a Poppins font.
