This is a scatter plot of the Iris dataset, mapping sepal length on the x-axis and petal length on the y-axis, with species indicated by different symbols. A custom legend encodes the species using shape scale from d3.scaleOrdinal and d3.symbolsFill. The visualization uses d3.v7, with axes created using d3.axisLeft and d3.axisBottom. Data is loaded from a remote CSV file and parsed with d3.csvParse. The chart updates based on the browser window size.
