This example displays a static flag composed of a white rectangle overlaid with a red rectangle and a circle outline, rendered as SVG elements in a 960-by-500 viewport. The design uses `d3.select` and `d3.append` from the D3 v4 library to construct the shapes, with data for the rectangles stored in an array. The circle is appended separately using explicit `cy`, `cx`, and `r` attributes rather than data-driven binding, and the code relies on D3’s selection and `append` methods without any interaction or animation.
