A scatter plot visualizes the Iris Dataset, mapping petal length on the x-axis and sepal width on the y-axis. Each point is colored by species using a d3.scaleOrdinal with a categorical color range. The visualization is rendered as an SVG using React, with axes generated by custom AxisBottom and AxisLeft components that use d3.scaleLinear and tick formatting via d3.format. Tooltips display the petal length value for each circle.
