A scatter plot of the Iris dataset, with color encoding species and dropdown menus to select which flower measurements appear on the x and y axes. The visualization uses React with hooks to manage state and D3 v6 scales for positioning axes and circles, rendered as SVG elements. Axis ticks and labels are generated manually with JSX, while the ordinal color scale maps the three species to a custom palette. Data loads asynchronously via d3.csv from a remote URL.
