This interactive scatter plot visualizes the Iris flower dataset, displaying measurements of sepal and petal dimensions across three species. Users can dynamically select which measurement appears on each axis through dropdown menus, with the chart redrawing to reflect the new configuration. The visualization uses D3.js v7 with SVG rendering, employing d3.scaleLinear for scales, d3.axisBottom and d3.axisLeft for axes, and d3.scaleOrdinal for color coding by species. The code loads data from a CSV file and includes a legend identifying the three species.
