This scatter plot visualizes the Iris dataset, mapping sepal length to the x-axis and sepal width to the y-axis. Each flower is rendered as a large blue circle using SVG within a React framework, with the plot area offset by margins via a group transform. The code loads data from a remote CSV file using D3’s `csv` function, converts values to numbers, and scales positions with `scaleLinear` and `extent`. The chart fills the browser window, as the body has no margin and hidden overflow.
