This interactive scatter plot visualizes Fisher's Iris dataset, allowing users to explore relationships between sepal and petal measurements across three iris species. Colored circles represent individual flowers, distinguished by species category. The visualization includes dropdown menus positioned along the axes for selecting which measurement is displayed on each axis. Built with D3.v7, the code utilizes `scaleLinear` for axis scaling, `scaleOrdinal` with `schemeCategory10` for color encoding, and custom D3 join operations to render axes, legend, and plot marks.
