This example shows an interactive scatterplot of the Iris dataset, plotting sepal width against sepal length. The visualization uses React to render SVG elements and d3.scaleLinear for both axes. Data is loaded asynchronously via d3.csv from a GitHub gist, with custom React components like AxisBottom, AxisLeftScatterChart, and CircleMarks composing the chart. The axes display tick marks and labels, while circles represent individual data points, all styled with CSS classes for a clean, readable layout.
