{"version":"1.0","type":"rich","title":"network and tree","description":"This example presents an interactive language family tree as a hierarchical visualization, showing the structure of Language Family → Language → Country with circle size encoding native speaker counts in millions. The SVG-based chart uses D3.js v7 to load CSV data from a GitHub gist, parsing a tokenized single-line format before building the hierarchy. Tree layout renders nodes and links, while hover interactions trigger a tooltip displaying additional details about each language.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/558ece00dd3847c58a7f3d079ac12b18?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
