A word cloud visualizes a hardcoded list of words (e.g., “Hello,” “Coding,” “Van”) from `words.js` and `data.csv`. The layout uses the `d3.layout.cloud` library, which employs an Archimedean spiral and collision detection to position words. Rendered as SVG and canvas, the words appear in steelblue with a text-anchor, and the animation (via `timeInterval` and `dispatch`) progressively places each term. The `index.js` code uses canvas `getImageData` for font metrics and a bitmask board for collision checks.
