This scatter plot visualizes the Iris dataset, mapping sepal length on the x-axis and petal length on the y-axis, with each species distinguished by a different symbol shape. The D3-based visualization uses `scaleLinear` and `scaleOrdinal` to map data dimensions, while `symbolsFill` and a custom symbol generator render the shape-encoded marks. An accompanying legend, built with `shapeLegend`, identifies each species, and axis labels clarify the measurements. The chart loads CSV data asynchronously and displays it across the full browser window.
