This scatter plot visualizes the Iris dataset, mapping petal width to sepal length and using distinct symbols for each species. It uses D3 v6 APIs including `scaleLinear`, `scaleOrdinal`, `symbol`, and `symbols` to render SVG paths, with axes generated via `axisLeft` and `axisBottom`. The chart is built through a reusable `scatterPlot` function configured with margin, size, and accessor methods. Data is loaded as CSV from a GitHub gist and parsed into numeric values.
