{"version":"1.0","type":"rich","title":"D3 Sol LeWitt pt2","description":"This example reproduces a Sol LeWitt wall drawing using D3.js and SVG rendering. It displays a grid of horizontal and vertical bars that intersect, with circular masks applied to create a rounded viewing window in the center of the canvas. The code uses D3’s `select`, `range`, and `join` APIs to generate the rect elements, and constructs two SVG masks—one with a white circle on black and another with a black circle on white—to reveal and conceal portions of the bars. The visualization fills the entire browser window, with the bars spaced at 20-pixel intervals.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ad36a5f330084b7e8cad86385eeada38?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
