This interactive scatter plot visualizes the Iris dataset, showcasing measurements of sepal and petal dimensions. Users can dynamically select which attributes to display on the X and Y axes via dropdown menus. Hovering over the color legend highlights a specific species, fading the remaining data points to emphasize the selected group. Built with React and D3 v5, the visualization renders as an SVG and uses `scaleLinear` for axis scaling and `scaleOrdinal` for categorical coloring.
