{"version":"1.0","type":"rich","title":"First D3 Viz","description":"This example creates a full-screen SVG pattern of intersecting horizontal and vertical bars, separated into two masked groups. D3’s `select` and `range` generate 100 rectangles per axis, while `symbol` and `symbols[7]` draw the star-shaped mask, and a circle forms the second mask. The masks reveal or hide parts of the grid, producing a geometric composition against a black-and-white backdrop. The visualization runs in a React framework using raw JavaScript and D3 v7, with no external data source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f7f7ff84c6c44d14813242bc911cb2fb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
