{"version":"1.0","type":"rich","title":"Simple_SolLettWittRecreation","description":"Two nested sets of d3-selected SVG rectangles form a subtle grid of vertical and horizontal lines, which is partially occluded by a circular mask. The entire composition is filled with a white overlay that uses the same circular mask, isolating the grid intersection in the center of the viewport. The code builds the 100 vertical and horizontal bars with `d3.range`, `selection.join`, and `selection.attr`, then applies a `<mask>` element with a centered circle to clip the background and horizontal lines against the vertical bars.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f200f560750448efa1885176bbe25cad?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
