This interactive scatterplot visualizes the Iris flower dataset, mapping sepal and petal measurements along the axes while coloring each point by species using a d3.scaleOrdinal. Users can switch between the four measurement attributes for either axis via React dropdown menus. The visualization uses d3.csv to load data, d3.scaleLinear for positioning, and renders SVG circles with native title tooltips, following Curran Kelleher’s code-along tutorial.
