This scatter plot visualizes the Iris dataset, showing sepal length against petal length, with species distinguished by different d3 symbol shapes. A shape legend identifies the three species categories, while labeled axes display the quantitative measurements. Built with D3 v7, the visualization uses modular JavaScript functions including `scaleLinear`, `scaleOrdinal`, `symbolGenerator`, and custom axis and legend components. The data is loaded asynchronously from a remote CSV file and parsed using `csvParse`, with the plot rendering across the full browser window.
