{"version":"1.0","type":"rich","title":"quilt block (random color)","description":"A grid of 1,500 small squares fills the screen, each cell randomly assigned a harmonious golden-ratio-based color from a custom HSL-to-RGB function. The visualization shows how a quilt-like pattern emerges from uniform geometry with varied fills. Built with D3 v4, the code generates row and column data arrays, then binds them to SVG rectangles using `selectAll`, `data`, and `enter`. The `randomColor` closure iterates through hues via the golden ratio, while white strokes separate each square, creating a subtle grid structure.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-71684611ee9f25d417dea96baaee9bcb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
