This interactive scatter plot displays the relationship between sepal length and petal length for three iris species, distinguishing each species with a distinct symbol shape and a legend. The visualization uses D3 v7 scales, axes, and reusable chart modules, with the scatterPlot component rendering SVG path marks via d3.symbol. The axis and legend components are composed using D3’s selection joins and call syntax. Data loads asynchronously from a remote CSV file, parsed with d3.csvParse, and scales are computed from extents using d3.scaleLinear and d3.scaleOrdinal.
