This example visualizes the Iris flower dataset, plotting petal length against sepal length as small circles. Each point is positioned using D3’s `scaleLinear` and `extent` to map data values to screen coordinates, with axes added via `axisBottom` and `axisLeft`. The SVG circles are rendered dynamically in React after loading the CSV, with margins and window-sized dimensions. Styling applies a font size and blue color to tick labels via CSS.
