This interactive scatter plot visualizes the Iris dataset, allowing users to compare any two numerical attributes by selecting variables for the X and Y axes from dropdown menus. Built with React and D3.js, the visualization uses `scaleLinear` and `extent` to map data values to SVG coordinates, with custom axis components rendering ticks. The marks are SVG circles with tooltips that show formatted values using D3's `format`. Data is loaded asynchronously via D3's `csv` parser, and the interface updates dynamically when menu selections change.
