{"version":"1.0","type":"rich","title":"quilt block (random texture)","description":"This example generates a 50-by-30 grid of colored and textured rectangles, forming a quilt-like pattern where vertical bands define colors and horizontal bands define texture patterns. The visualization uses D3 v4 with SVG rendering, plus the textures library to create circle and path-based patterns. A nested ordinal scale maps three color categories from ColorBrewer to three texture generators, applying each texture in each color. The code initializes texture definitions using D3’s selection `.call` method, then binds grid data to rectangles positioned in a fixed 25-pixel cell layout.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-5e0b4e677e74f22a01da902a423c7c41?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
