This scatterplot visualizes the Iris dataset, plotting sepal length on the x-axis against sepal width on the y-axis for each flower sample. The visualization uses React to render SVG circles within an HTML5 page, while D3 version 5 utilities—including `csv`, `scaleLinear`, `extent`, and `max`—handle data loading, scaling, and axis generation. Axis components leverage D3’s tick generation, with formatted labels and grid lines. Selections display tooltips via SVG `<title>` elements, and the layout employs fixed margins with Poppins typography for a polished presentation.
