This interactive scatter plot visualizes the Iris dataset, mapping sepal length on the x-axis and petal length on the y-axis while distinguishing species through different symbols. The chart uses D3 v7’s `scaleLinear` for axes, `scaleOrdinal` with `symbolsFill` for shape encoding, and a custom legend module. Data is loaded asynchronously via `fetch` and parsed with `csvParse`, with axes rendered using `axisLeft` and `axisBottom`. The visualization updates dynamically as the data arrives, demonstrating categorical shape encoding for multivariate comparison.
