This example shows a scatter plot of the Iris Dataset, mapping petal width to the x-axis and sepal length to the y-axis. The visualization uses D3 v6 APIs including `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to render axes and circles. The chart is implemented as a reusable function, taking data, dimensions, margins, and accessor functions as configurable properties. It renders full-screen as an SVG, with each data point drawn as a circle with a fixed radius of 5 pixels.
