This scatter plot visualizes the Iris dataset, showing the relationship between sepal length and petal length for three species, distinguished by shape. The plot uses D3.js v7 with `scaleLinear` and `scaleOrdinal` to map data to positions and symbolic shapes from `symbolsFill`. A shape legend displays each species. Data is loaded from a remote CSV file and parsed with `csvParse`, with the axes and legend created using D3's `axisLeft`, `axisBottom`, and custom shape legend components.
