This interactive scatterplot visualizes the Iris dataset, letting users explore relationships between sepal and petal measurements while distinguishing species by color and symbol. Built with D3 v7 in React, it uses `scaleLinear` and `scalePoint` for quantitative and categorical axes, with `scaleOrdinal` mapping species to colors and symbol types. Dropdown menus, powered by a reusable `menu` component with `dispatch`, dynamically update the x and y axes. Circles animate position changes via `transition().duration(1000)`, and axis labels update accordingly, all rendered as SVG.
