SVG Fundamentaks
This example demonstrates basic SVG shape creation using D3.js version 3. It renders a single circle element inside an SVG container within an HTML page. The visualization relies on D3’s SVG manipulation capabilities, specifically the `d3.select` and `d3.append` methods to create and insert the circle into the document. The code defines the SVG namespace implicitly through D3’s helper functions, with no data binding or animation present—only the static geometric primitive. The rendering approach is direct SVG output, as indicated by the `rendering: svg` metadata.
