This interactive scatter plot displays measurements from the famous Iris dataset, with dropdown menus allowing users to select which four numeric attributes (sepal length, sepal width, petal length, petal width) appear on the x and y axes. Each point represents a flower, color-coded by species. Built with D3 v7 and React, the SVG visualization uses `d3.scaleLinear` for axes, `d3.axisBottom` and `d3.axisLeft` for ticks, and `transition().duration(2000)` to animate points smoothly to new positions when selections change.
