This interactive scatter plot displays the relationship between sepal length and petal length for three iris species, distinguished by different D3 symbol shapes. Using d3.scaleLinear for axes and d3.scaleOrdinal with symbolsFill for shapes, it renders SVG paths via the d3.symbol generator. A custom shapeLegend displays species categories. Data is loaded asynchronously via fetch and parsed with d3.csvParse from a remote CSV file, with numeric fields converted before plotting.
