This interactive scatter plot visualizes the Iris dataset, letting users explore relationships between four measurements (sepal and petal length/width) through dropdown menus that select which attribute appears on each axis. The visualization renders as an SVG using React components, with D3 v5 handling data loading via `d3.csv` and scale construction through `scaleLinear` and `extent`. Axis ticks are generated manually from the scales, and hovering over a point reveals its x-value via an SVG `<title>` element. The chart includes styled axes, labels, and a clean layout with margins.
