This scatter plot shows the relationship between sepal length and petal length for three iris species, with each species distinguished by a different symbol shape and a legend labeling the categories. The visualization loads CSV data from a GitHub-hosted iris dataset and uses D3 v7 APIs including `scaleLinear`, `scaleOrdinal`, `symbol`, and `axisBottom`/`axisLeft` to render the axes and symbols. The legend is built by appending paths and text elements within a dedicated group, while the chart updates responsively to the window size.
