This interactive scatter plot displays the Iris dataset, allowing users to explore relationships between sepal and petal measurements through drop-down menus that select which attribute appears on each axis. Points are colored by species using d3.scaleOrdinal, with circles rendered as SVG marks that include tooltips showing values. Built with React and D3 v7, the visualization uses React state to manage selected attributes and re-scale axes via d3.scaleLinear, with custom axis components generating ticks and labels.
