This scatter plot visualizes the Iris dataset, plotting sepal length on the x-axis against sepal width on the y-axis for individual flower samples. Each data point is rendered as a circle, with a native HTML tooltip revealing the sepal length value on hover. The visualization is built with React and D3 v7, using `d3.scaleLinear` and `d3.extent` to map data to SVG coordinates, while custom React components handle axis rendering. The data is loaded asynchronously via `d3.csv` from a remote URL.
