This work recreates a Sol LeWitt-inspired generative drawing as an animated SVG. It shows a shifting field of circles whose positions and radii oscillate along a sine wave, creating a flowing, rhythmic pattern across the browser window. The animation is driven by `setInterval` updating a time variable, with the D3.js library’s `select`, `range`, and `join` operations building the circles dynamically each frame. Data is synthesized in `makeData.js`, while `vizData.js` handles the visual rendering.
