{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This example visualizes a hierarchical tree of function calls from a C codebase, with the root “main” branching into manager functions and their nested subroutines. The data, loaded from a JSON file, is displayed using D3 v5’s `tree` layout and `hierarchy` function, with nodes connected by `linkHorizontal` paths. Panning and zooming are enabled via `d3.zoom`, and the SVG text labels carry file paths and function names. The visual uses a teal stroke and serif typography to present the call graph clearly.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a7fa2722f14f4363a4dd9e465027dd25?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
