A scatter plot of the Iris Dataset displays sepal length against petal length for 150 flowers, with points colored by species using a categorical color scale. A legend identifies the three species, and labeled axes provide context. The visualization uses D3 v7 with modular functions for drawing axes, applying scales, and rendering circles. The color encoding uses `scaleOrdinal` and `schemeCategory10`, while data loads asynchronously from a CSV file via `csvParse`.
