This interactive scatter plot visualizes the Iris dataset, mapping petal length and width for individual data points, with each point colored by species (setosa in red, versicolor in blue, and virginica in green). It also encodes sepal dimensions in the horizontal and vertical radii of each circular mark, creating a bubble-like effect. Built with React and D3 v6, the code uses `d3.csv` for data loading, `scaleLinear` and `extent` for scaling, and `axisLeft`/`axisBottom` for axes, rendering everything as SVG circles on a full-window canvas. The data is fetched from a remote GitHub gist.
