This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal measurements across three flower species. Two dropdown menus control which measurements appear on the x and y axes, while a color legend enables highlighting individual species by dimming others. Built with React and D3 v5, the visualization uses `scaleLinear` for axes, `scaleOrdinal` for categorical colors, and renders SVG circles positioned via x and y scales, with native tooltips on hover.
