{"version":"1.0","type":"rich","title":"Vertical Tree Diagram with Rectangles","description":"A vertical tree diagram visualizes a food hierarchy using rectangles for nodes, starting with \"Food\" and branching into Vegetables and Fruits, then further into specific items like Spinach and Apple. The D3.js v7 code uses `d3.hierarchy` to process the nested JSON data and `d3.tree` to compute the layout. SVG paths with curved bezier links connect the nodes, while styled rectangles and text labels render each element with colors defined in CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/558117c773084731bff1cfcf7f3e462f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
