This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between four flower measurements (sepal and petal length/width) and species. Two dropdown menus, implemented as React components, let viewers independently select which attributes appear on the x- and y-axes. The visualization uses d3.scaleLinear for coordinate mapping, with React managing state updates and SVG rendering ticks, circles, and axis labels. Data loads asynchronously via d3.csv from a remote gist, and each data point includes a tooltip showing its exact value.
