{"version":"1.0","type":"rich","title":"Tree","description":"This interactive tree visualization displays the hierarchical relationships within Hospital ER data, using a radial layout to reveal parent-child connections. Built with D3.js v7 and React, it renders nodes as colored rectangles and circles, with each node’s size and color varying by depth. The code loads a remote CSV, stratifies it into a tree using `d3.stratify()`, positions nodes via `d3.tree()`, and draws links with `d3.linkVertical()`. Node coordinates come from the tree layout, with labels showing ER names.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/624e4874bdf34fa588c7a44fb16f474e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
