A React-based scatter plot visualizes the Iris Dataset, showing petal length against sepal width. The visualization uses d3.scaleLinear for both axes, with formatted tick labels and axis labels. Data loads via d3.csv from a GitHub gist, parsing numeric values for all four iris measurements. The SVG rendering displays circles for each data point, with hover tooltips showing petal length values. The chart uses a Poppins font and custom styling for ticks, marks, and axis labels, with a responsive design that centers the visualization in the viewport.
