{"version":"1.0","type":"rich","title":"Fourth Class","description":"This example recreates a Sol LeWitt-style geometric composition using two overlapping sets of striped rectangles: one set of horizontal bars and one of vertical bars. The bars are selectively revealed through two circular SVG masks, creating a layered grid pattern with a central circular intersection. The visualization is built with D3.js, using `select`, `range`, and data joins to generate 100 rectangles in each direction, and `mask` elements with `circle` shapes to control visibility. The piece is rendered as an SVG that fills the entire browser window.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/edd3958b9d9c451caa9dd8fbc6d66c90?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
