This scatter plot visualizes the Iris dataset, showing the relationship between sepal length and petal length, with points shaped according to species. The chart uses d3.scaleLinear for axes and d3.scaleOrdinal with d3.symbolsFill to map species to distinct shapes, rendered via d3.symbol. A custom shape legend clarifies the species mapping. Data is loaded asynchronously from a CSV file hosted on GitHub, parsed with d3.csvParse, and rendered using D3’s join operation within a React starter framework.
