This example displays a set of circles arranged in a simple scatterplot-like layout within an SVG container. The visualization uses D3 v4 to bind data points to circle elements, positioning them with static coordinates and styling them with default attributes. The code relies on D3’s selection and data-join methods, such as `d3.select` and `append`, to create the circles dynamically. It does not include any interactive behavior or transitions, presenting a straightforward static rendering of circles as a foundational demonstration of D3’s SVG capabilities.
