This example visualizes the Iris Dataset with a scatter plot mapping sepal length to the x-axis and petal length to the y-axis. Dots are colored by species using a categorical color scale, with a legend positioned in the upper right. The visualization is built with D3 v7, using `scaleLinear`, `scaleOrdinal`, `schemeCategory10`, and `selection.join` for rendering. Axes and labels are added via custom modules, and data is loaded asynchronously from a CSV file and parsed with `csvParse`.
