{"version":"1.0","type":"rich","title":"d3 art","description":"This example renders a series of red horizontal rectangles across the full screen using SVG, with each rectangle positioned at a fixed y-coordinate. The code builds an array of mark objects and uses D3 v5's `select`, `range`, and `append` methods to create the shapes, while the HTML page loads D3 from a CDN. The visualization is minimal, showing only stacked red bands without interaction or animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/833ea15c60ab49718fef19374ef7e0d8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
