{"version":"1.0","type":"rich","title":"SVG Fundamentals","description":"An SVG-based visualization demonstrates how masking layers create intersecting geometric patterns. The code renders 100 horizontal and vertical rectangles using D3's `select` and `range`, each masked by a circular region. Two SVG masks invert their black-and-white fills, producing a visible cross-shaped overlap at the center where the circles align. The grid lines only appear within the masked circular areas, creating a dynamic interplay of light and dark stripes against a blank canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a9bfeb636adc4ea98e56d0e00f39f5cd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
