A scatter plot visualizes the Iris dataset, showing petal length on the x-axis and sepal width on the y-axis for individual flower samples. The visualization uses React components to render the SVG elements, with d3.scaleLinear handling the axis scales and d3.extent computing the data domains. The code defines reusable AxisBottom, AxisLeft, and Marks components, applying Poppins typography and a teal color scheme with subtle grey grid lines. Each circle includes a native SVG title element for hover tooltips displaying the formatted x-axis value.
