A scatter plot of the Iris dataset maps petal length against sepal width, with points colored by species using a d3.scaleOrdinal. The visualization is built in React with SVG rendering, using d3-scale for the axis scales and d3-format for tick labels. A custom useData hook loads and parses the CSV dataset, while AxisBottom, AxisLeft, and Marks components render the axes and circles. Each circle includes a native SVG title element for hover tooltips.
