This visualization is a scatter plot of the Iris dataset, displaying the relationship between petal width and sepal length, with points colored by species. It uses a reusable D3 module (scatterPlot) that applies linear scales, an ordinal color scale, and SVG symbols to render the data. The chart fetches the dataset from a Gist URL, parses numeric fields, and draws axes with d3’s axisLeft and axisBottom, while the symbol size is set to 100. The code demonstrates a configurable chart function with settable properties like width, height, and margins.
