Mathematical Graphic Patterns

A grid of 30 by 30 small circles continuously shifts and morphs in an animated screensaver-like display. Each circle’s position and size are driven by sine and cosine functions of its grid coordinates and a continually advancing time value, producing swirling, geometric motion. The code uses Canvas drawing APIs such as `getContext('2d')`, `beginPath`, `arc`, and `fill` to render the circles, with colors computed via a custom `rgb` function based on grid position and time. The animation runs through `requestAnimationFrame`, and the canvas resizes to match the window dimensions.

Let's Make a Face Part I

This example builds a simple smiley face using SVG primitives. It shows a large yellow circle as the head, with two smaller black circles positioned inside it to represent eyes. The visualization is created entirely with static SVG elements, including explicit `cx`, `cy`, `r`, `fill`, and `stroke` attributes. The rendering relies on the browser’s native SVG support, with no external JavaScript libraries or data sources involved. The layout is fixed within a 960×500 viewport, and the face is centered accordingly.
