This scatter chart displays iris flower measurements, plotting sepal length against sepal width. Each flower is represented by a fixed-size circular mark, with a native SVG `<title>` element providing tooltips on hover. The visualization uses React to manage component structure, while D3 v5’s `scaleLinear` and `extent` functions handle axis scaling and domain calculation. Data is loaded asynchronously from a CSV file via `d3.csv`, and axes are rendered as custom React components that generate SVG ticks and gridlines.
