This example uses the classic Iris dataset to create a scatter plot, mapping petal width on the x-axis and sepal length on the y-axis. The visualization is rendered as an SVG using D3.js v6, employing the `scaleLinear`, `axisLeft`, `axisBottom`, `scaleOrdinal`, and `symbol` APIs to position and shape the data points. The plot includes styled axis labels for both dimensions and a main title, with categorical species represented by distinct symbol types. Data is loaded asynchronously from a CSV file fetched via the `csv` function.
