This example displays the Iris dataset as a scatter plot, with sepal length and width mapped to the x- and y-axes. The visualization uses React to render SVG elements, including circular marks for each data point, styled with the Poppins font and custom colors. Axis tick marks and labels are generated using d3.scaleLinear and d3.format APIs, while d3.csv loads the data from a remote file. Tooltips reveal the precise sepal length value when hovering over a circle.
