{"version":"1.0","type":"rich","title":"Fork of Fork of Fork of Fork of React Starter","description":"A web page displays a grid of horizontal and vertical black bars overlaid with two circular SVG masks, creating a crosshatch pattern that is visible only within two intersecting circular regions. Using React 18 and D3's `select` and `range`, the code appends an SVG canvas sized to the viewport and generates 100 rectangles in each orientation. The masks, defined via `svg.append('mask')`, combine white and black circles to control visibility, producing a stark geometric composition centered on the screen.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/608f7f3160c844b8bef503a64e7657f1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
