This example is a reusable scatter plot that visualizes the Iris Dataset, using distinct symbols to represent different species. The plot maps petal width to the x-axis and sepal length to the y-axis, with axis labels rendered via `d3.axisLeft` and `d3.axisBottom`. The implementation leverages `d3.scaleLinear`, `d3.scaleOrdinal`, and `d3.symbol` to generate SVG paths for each data point. Data is loaded asynchronously from a CSV file using `d3.csv` and parsed with a custom row handler. The plot’s dimensions adapt to the browser window, and styling is applied through a linked stylesheet.
