This interactive scatterplot visualizes the Iris flower dataset, allowing users to explore relationships between four measured attributes by selecting which features appear on the x- and y-axes via dropdown menus. The SVG renderings use D3 scales (scaleLinear, scaleOrdinal) for positioning and coloring data points by species, while React components manage the axes, legends, and interactive state. Hovering over the color legend highlights points of a specific species by dimming all others, with the color legend implemented as an interactive React component that triggers hover events.
