This interactive scatter plot displays sepal length against sepal width for the classic Iris dataset, with each of the 150 flowers represented as a teal circle positioned by linear scales. The visualization includes labeled axes with formatted tick marks and hover tooltips that reveal exact sepal length values. Built with React and D3 v7, the code uses d3.scaleLinear and d3.extent to map data coordinates to SVG space, while custom React components (AxisBottom, AxisLeft, and Marks) render the axes and circles from CSV data loaded via d3.csv.
