This scatter plot visualizes the Iris Dataset, mapping petal length and sepal width for individual flowers, with color encoding species. Built with React and D3 v5, it uses `scaleLinear` for axes and `scaleOrdinal` for the categorical color scale. A custom `ColorLegend` supports interactive hover, which dims non-matching points and re-renders the highlighted subset. Axes are generated via reusable `AxisBottom` and `AxisLeft` components, while SVG circles serve as marks.
