This scatterplot visualizes the Iris dataset, plotting petal length against sepal width for individual flowers. The visualization renders as an SVG using React components, with D3 v7 handling the data loading via `d3.csv` and the linear scales for the axes. Each data point is a circle generated through React components, with tooltips displaying the x-axis value in a compact format. The chart includes labeled axes for petal length and sepal width, and uses `scaleLinear` with `extent` and `max` to compute the scale domains.
