This scatter plot visualizes the Iris dataset, showing the relationship between petal width and sepal length. The chart uses D3.js 6.7.0 APIs like `scaleLinear`, `scaleOrdinal`, `axisLeft`, and `axisBottom` to map data points to positions and render axes. Each species is represented by a distinct symbol from D3's `symbols` generator, with all points filled brown. The plot is rendered as an SVG directly in the browser, sized to the full window dimensions. The data is loaded from a remote CSV file via D3's `csv` function.
