This interactive scatter plot visualizes the classic Iris dataset, displaying the relationship between two user-selected measurements (such as sepal length and petal width) for 150 flowers across three species. Points are color-coded by species, with a legend and labeled axes included. The visualization uses D3 v5 with SVG rendering, employing scales like `d3.scaleLinear` and `d3.scaleOrdinal`, along with `d3.axisBottom` and `d3.axisLeft` for the axes. Dropdown menus allow users to dynamically change which data columns are plotted.
