An interactive scatter plot explores the classic Iris dataset by Fisher, visualizing measurements of sepal and petal dimensions across three flower species. Dropdown menus allow the user to select which attributes appear on the x and y axes, while a color legend distinguishes species and fades non-hovered points. Built with React and D3 v5, the visualization uses `d3.scaleLinear` for axes, `d3.scaleOrdinal` for categorical colors, and renders marks as SVG circles with tooltips.
