{"version":"1.0","type":"rich","title":"Tree","description":"This example shows a hierarchical tree diagram built from a CSV file listing parent-child relationships between defect types and priority categories. The visualization uses D3.js’s `d3.layout.tree` and `d3.svg.diagonal` to position nodes and draw curved links, with SVG rendering for circles and labels. The data, loaded via `d3.csv`, is converted from a flat structure into a nested tree and displayed with a fixed-depth layout, where each level represents a different category of items.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5f76d7ee02864909bba5bed71953809e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
