This reusable D3 scatter plot visualizes the Iris Dataset, showing the relationship between petal width and sepal length with distinct symbols for each species. Built with a custom scatterPlot function, it uses D3's `scaleLinear` and `scaleOrdinal` for axes and symbol scaling, `axisLeft` and `axisBottom` for axis rendering, and `symbol().size()` to generate varied path shapes. The SVG output fills the browser window, with margins and a fixed symbol size of 100, while the data is parsed from a remote CSV, converting numeric columns to numbers before plotting.
