This example visualizes the classic Iris Dataset, plotting petal width against petal length for 150 individual flowers. The scatter plot uses `d3.scaleLinear` to map data extents to screen coordinates, with circles colored by a random HSL hue at partial opacity. The code loads the CSV file via `fetch` and parses it with `csvParse`, then renders the visualization using D3 v7 selection joins. Custom axes are created with `d3.axisLeft` and `d3.axisBottom`, with white labels for petal-length and petal-width.
