This fork of a D3 scatter plot visualizes the classic Iris dataset, plotting sepal length against sepal width and coloring each point by flower species. Users can hover over legend items to highlight corresponding data points, which receive a black outline and full opacity. Built with React and d3.v7, it uses the d3-rosetta library’s unidirectional data flow pattern to manage rendering and state. The chart features linear scales, axes via `axisBottom` and `axisLeft`, a categorical color scheme, and a loading state while parsing the CSV file.
