{"version":"1.0","type":"rich","title":"Tree Chart","description":"This tree chart visualizes a hierarchical dataset of continents, countries, cities, and landmarks, using color-coded nodes to distinguish each level. The SVG visualization is built with D3.js version 3.5.17, employing the `d3.layout.tree` for node positioning and `d3.svg.diagonal` for curved connecting links. The interactive animation reveals the structure progressively, with each parent node expanding to display its children over a one-second duration. Data is hardcoded in the `plantGenerationsData` array, and the rendering uses a white node fill with steelblue strokes against gray links.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d0e0b21717704b5db3d308391687b71f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
