{"version":"1.0","type":"rich","title":"Fork of Collapsible Tree Version 1_modify","description":"This interactive collapsible tree visualization displays a Korean AI startup ecosystem, hierarchically organized from the root category \"인공지능\" through industry and field subcategories down to individual company names. The data is loaded from both a CSV file and JSON, with the tree structure built using `d3.hierarchy` and `d3.tree`. Users can click any node to expand or collapse its child branches, with smooth transitions animated by `transition.attrTween` and node repositioning via `d3.linkHorizontal`. The visualization is rendered as an SVG with zoom support, and node updates use enter, update, and exit selections to handle dynamic hierarchy changes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/db8f48fe59a04107927181d9fb08bf5d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
