This interactive scatter plot visualizes the classic Iris dataset, letting users explore relationships between sepal and petal measurements by switching axes via dropdown menus. Built with D3 v7, the visualization supports both numerical and categorical axes, with circles transitioning smoothly between positions using `d3.transition`. The scatter plot component uses `scaleLinear` and `scalePoint` for scaling, while SVG rendering and axis generation via `axisLeft` and `axisBottom` update dynamically as selections change.
