This scatterplot visualizes the relationship between petal length and sepal width in the Iris dataset, with each circle representing a flower sample. The React-based visualization uses D3 utilities to load CSV data, compute linear scales, and generate SVG axes and marks. Circles are rendered with native SVG elements, and tooltips display formatted values via the `title` attribute. The chart applies `.nice()` to the x-scale, custom tick formatting, and labeled axes to clarify the data dimensions.
