SVG fundamentals
This example demonstrates fundamental SVG rendering with a series of four circles displayed in a row, each with a radius of 50 units. The first circle is unfilled, while the subsequent circles use red, green, and blue fills. The page is built with a minimal HTML structure that embeds the SVG directly in markup, with basic CSS styling for a large text greeting message. It utilizes raw SVG circle elements without any JavaScript libraries or data processing.
