This scatter plot shows the relationship between sepal length and petal length for three iris species, with each species distinguished by a unique symbol shape and a corresponding legend. The visualization uses d3.scaleLinear for the x and y axes, d3.scaleOrdinal to map species to d3.symbolsFill shapes, and d3.axisLeft and d3.axisBottom for the axes. Data is loaded asynchronously from a CSV file and parsed with d3.csvParse, with the chart rendered using D3 v7’s data join pattern.
