{"version":"1.0","type":"rich","title":"D3_First_Exercise","description":"A full-screen SVG grid of thin black horizontal and vertical lines is masked to reveal two offset circular cutouts in the center of the canvas. The piece is a direct reproduction of a Sol LeWitt art concept, rendered using D3 v6. The code builds the lines by binding `d3.range(n)` data arrays to `rect` elements via `.join()`, while two layered SVG `<mask>` elements (one black rect with white circle, one white rect with black circle) define the visible apertures.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6a481abd22f54129a68b440d900cb762?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
