This interactive scatter plot visualizes the Iris dataset, mapping sepal length on the x-axis and petal length on the y-axis, with species distinguished by different symbol shapes. The visualization uses D3.js v7, employing `scaleLinear` for both axes, `scaleOrdinal` with `symbolsFill` for shape encoding, and a custom shape legend component. Data is loaded asynchronously from a GitHub-hosted CSV file using `d3.csvParse`. The chart responds to window resizing by redrawing within the full viewport, with axes and labels generated through reusable `axes.js` and `scatterPlot.js` modules.
