{"version":"1.0","type":"rich","title":"Basic Tree Map","description":"This visualization shows a hierarchical tree map of world regions and countries, with the root labeled \"World\" branching into continents and subregions before reaching individual nations. The layout positions nodes horizontally, with parent-child relationships drawn as curved links using the `linkHorizontal` path generator. The visualization loads data from a local JSON file and uses D3 v5's `tree` and `hierarchy` functions to compute the layout, while SVG elements are selected and managed with `select` and `selectAll`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7e4140e9bd8f4406af2e8333dd32a371?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
