This scatter plot visualizes the relationship between sepal length and petal length for Iris flower species, using distinct symbol shapes to differentiate species categories. The D3 v7 implementation uses `scaleLinear` for both axes, `scaleOrdinal` with `symbolsFill` for shape encoding, and a custom legend component. Data is loaded asynchronously from a remote CSV file and parsed with `csvParse`. The chart includes labeled axes and a shape-based legend, with symbols rendered using the `symbol` generator at a fixed size.
