This example demonstrates basic SVG rendering with D3 version 7, showing two static circles positioned on a 960×500 canvas. The code directly embeds SVG circle elements in the HTML, using attributes like `cx`, `cy`, and `r` to control placement and size, with the second circle given a red fill. While it includes an empty D3 import and a commented-out text selection, the visualization primarily relies on native SVG markup rather than D3’s data-joining or selection APIs. The page loads d3.min.js from the unpkg CDN, though no dynamic data or interactive behavior is currently active.
