This interactive scatterplot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal measurements across flower species. Two dropdown menus dynamically select which numeric attributes appear on the x and y axes, with the chart updating through React state management. The visualization uses d3.scaleLinear for both axes, d3.extent for domain calculation, and renders SVG circles through a reusable Bars component. Data loads asynchronously via d3.csv from a remote gist, with axis ticks styled through CSS classes and formatted using d3.format.
