This scatter plot displays Iris flower measurements, mapping sepal length to the x-axis and petal length to the y-axis. Each point’s shape encodes the species of the flower, with a legend showing which shape corresponds to which species. The visualization uses D3 v7 with modules like `scaleLinear`, `scaleOrdinal`, and `symbol` to render marks and axes. Data is loaded asynchronously from a remote CSV file and parsed using `csvParse`, with numeric fields converted before plotting.
