{"version":"1.0","type":"rich","title":"fresh block","description":"The visualization renders the French flag as three vertical rectangles using D3 v4's data-join pattern. It binds an array of objects containing fill colors and x-coordinates to SVG `rect` elements, then enters and appends each rectangle with explicit width, height, and positioning attributes. The code demonstrates a reusable data-driven approach to drawing multiple shapes, contrasting with earlier commented-out manual append commands. The SVG canvas is 960 by 500 pixels, with rectangles sized at 200 by 400 pixels and spaced along the x-axis.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-b7ee3406a9192f5f98edb60c25dd8508?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
