This interactive scatter plot visualizes the Iris dataset, showing the relationship between sepal and petal measurements across three flower species. Users select which measurements to plot on the x and y axes via dropdown menus, with matching options disabled to prevent duplicate axes. The visualization uses D3 v7 with SVG rendering, employing `scaleLinear`, `axisBottom`, `axisLeft`, and `scaleOrdinal` for color-coding species. Each selection change removes the existing graph and calls a `render` function to rebuild the plot with new scales and axes.
