This scatter plot visualizes the Iris Dataset, mapping petal length and sepal width for individual flowers. Each circle is colored by species using a categorical scale, with a legend displaying the three species names. The React application uses d3’s `scaleLinear` for axes, `scaleOrdinal` for colors, and `csv` to load data. Axes, marks, and the legend are rendered as SVG components, and hovering shows a tooltip with the x-axis value.
