This interactive scatter plot visualizes the Iris dataset, mapping petal length against sepal width. Points are colored by species, and hovering over a color legend entry filters the displayed points to that species. The visualization uses React with D3 v5 for scales and axes, rendering SVGs with custom components like `AxisBottom`, `AxisLeft`, and `ColorLegend`. Data is loaded via D3’s `csv` function, and ordinal color scaling assigns distinct hues to each species.
