{"version":"1.0","type":"rich","title":"d3.js journey","description":"Six horizontal black rectangles of varying widths sit on a white canvas, demonstrating basic SVG shape construction. Each rectangle is positioned by explicit x and y coordinates and fixed height values, creating a simple bar-like composition. The visualization uses raw SVG elements—specifically `<rect>` tags—within an HTML document, with no JavaScript or D3.js library present. The example highlights how static shapes can be defined directly in markup with precise sizing and placement attributes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/916796733ec84ae1b1418b23dac593b2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
