{"version":"1.0","type":"rich","title":"D3 Starter","description":"This example demonstrates generating a grid of horizontal and vertical lines across the full browser window, masked by two circular cutouts. The alternating line orientations create a crosshatch pattern that appears only within the circular regions, leaving the rest of the canvas blank. The visualization uses D3's `select` and `range` functions to append SVG `rect` elements, with masks (`circle-mask` and `circle-mask-2`) defining the visible areas. The code highlights the declarative D3 API for data-driven element creation and SVG attribute manipulation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/230d8de117a845d5b30e39172e9d7318?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
