This example presents a reusable scatter plot that visualizes the relationship between petal width and sepal length from a dataset loaded via `d3.csv`. The SVG visualization, rendered through a custom `scatterPlot` module, uses `scaleLinear` for axis scaling and `axisLeft`/`axisBottom` for tick marks. Data points are drawn as circles with configurable radius, and the plot adapts to the full browser window dimensions. The code leverages D3's `select` and `join` operations for efficient element creation.
