{"version":"1.0","type":"rich","title":"Working with D3","description":"This example creates a grid of horizontal and vertical stripes that are visible only through a circular aperture in the center of the canvas. Horizontal rectangles are masked by a circle of white on black, while vertical rectangles are masked by a black circle on white, revealing the underlying pattern. The code uses D3’s `select`, `range`, and `join` methods to generate the SVG rects and masks, setting widths to the full window and heights to 500 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/507f7250cbc9460294a5cf8d013b6a10?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
