This scatter plot visualizes the relationship between sepal length and sepal width in the classic Iris dataset, loaded via `d3.csv`. The SVG chart uses `d3.scaleLinear` with `.nice()` to set axes, rendered through React components (`AxisBottom`, `AxisLeft`) and circle marks with tooltips. The `scaleLinear` domains derive from `d3.extent`, while tick labels use `d3.format` for compact display. The iris data originates from a GitHub gist URL, parsed with numeric coercion in a row function.
