This interactive scatter plot visualizes the Iris dataset, mapping petal length on the x-axis against sepal width on the y-axis with circular marks. Built with React and D3 v5, it uses `scaleLinear` for both axes, `extent` for domain calculation, and custom SVG components for rendering axes and circles with tooltips. The visualization loads data via `d3.csv` from a GitHub gist and applies a custom `format` function for tick labels, styled with the Poppins font.
