The visualization uses a D3 tree layout with `d3.hierarchy` and `d3.tree` to compute node positions, and `d3.linkHorizontal` to draw the curved connecting paths. Data is loaded from a local JSON file, and the SVG canvas is sized to the full browser viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/534173feeee04b48920c9c5a71b6d2ea?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
