{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This example displays a hierarchical tree visualization of an SPDX software bill of materials, showing the PSReadLine package with its individual files and their corresponding SHA-1 and SHA-256 checksum values. The tree layout is rendered using D3 v5 with SVG elements, connecting nodes with horizontal link paths generated by `linkHorizontal`. Data is loaded from a local JSON file using `json()`, while the hierarchy structure is processed through `hierarchy()` and the tree layout function. The visualization uses a Playfair Display font with a fixed viewport and custom margins.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b2066f9f61d04451a9fb3ad9640bd36f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
