This example visualizes the Iris dataset as a scatter plot, mapping petal length and width on the axes while coloring each point by species (setosa, versicolor, or virginica). The chart uses D3 v6 to load CSV data, apply linear scales, and render SVG circles with custom fill colors. Axis labels are added using d3.axisLeft and d3.axisBottom, and the graphic fills the browser window. The code imports specific D3 modules via destructuring and uses scaleLinear, extent, and join for efficient data binding.
