This interactive scatter plot visualizes the Iris dataset, mapping sepal length against petal length, with points colored by species according to a shape legend. Built with React and D3 v7, it uses `scaleLinear` for axes, `scaleOrdinal` and `symbolsFill` for categorical shape encoding, and `axisLeft`/`axisBottom` for labeled axes. The plot dynamically updates its size to fit the viewport, fetching data from a raw GitHub CSV file hosted by the author.
