This scatter plot visualizes the relationship between sepal length and sepal width in the Iris dataset. The React and D3 v5 code uses `scaleLinear` to map data values to SVG coordinates, with custom `AxisBottom` and `AxisLeft` components rendering ticks and labels. Each flower is drawn as a circle with a `title` element providing a native browser tooltip. Data loads asynchronously via D3’s `csv` function from a remote GitHub gist.
