A yellow circle with a black outline and two smaller black circles forms a simple smiley face, though only the eyes are present; the mouth is absent. The visualization uses only static Scalable Vector Graphics (SVG) elements defined directly in the HTML, including three `circle` elements with explicit `cx`, `cy`, `r`, `fill`, and `stroke` attributes. No external libraries are employed, and no data is loaded; the rendering is purely declarative markup within a single HTML page.
