This example displays a static collection of eight circles of varying sizes, colors, and positions within a fixed SVG canvas. Each circle is defined with explicit `cx`, `cy`, `r`, `stroke`, `stroke-width`, and `fill` attributes, using hardcoded hexadecimal and named color values. The visualization is rendered directly via inline SVG markup, with styling handled by external CSS that centers the graphic on the page. The page also loads a JavaScript file that currently only logs "hello world" to the console, indicating no additional interactive or data-driven behavior.
