This example demonstrates a scatterplot visualization of the Iris dataset, showing the relationships between sepal and petal measurements across three flower species. The visualization uses D3.js (d3.v4) with an SVG rendering approach, implementing multiple scatterplots to compare different attribute combinations. The code employs d3.scaleLinear for axis scaling, d3.scaleOrdinal with a categorical color scheme for species differentiation, and d3.axisBottom/Left for tick marks. The iris data is loaded from a CSV file and mapped to separate plot regions within a single SVG canvas.
