{"version":"1.0","type":"rich","title":"d3NoobV5 Reusable Examples - Tree Diagram v2","description":"This example shows a vertical tree diagram built with D3.js v5, displaying hierarchical data as linked nodes with circles and text labels. It uses `d3.hierarchy` and `d3.tree` to compute the layout, with curved paths generated via SVG path strings for the links. The chart is implemented as a reusable module following the ProD3 pattern, with configurable dimensions, margins, and title. Data comes from a hardcoded JavaScript object, and the visualization renders entirely in SVG within a responsive container. The code also includes CSS styling for node circles, text, and link strokes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7449afeafee245e28b994f37fb2a29da?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
