{"version":"1.0","type":"rich","title":"tree","description":"This example shows a vertical tree diagram that categorizes mobile phones by operating system, with Android, iOS, and Others as the three main branches. The tree layout uses `d3.tree()` to position the hierarchy from top to bottom, with root nodes colored by depth using a `d3.scaleOrdinal()` color scheme. Data is defined inline as a JavaScript object and rendered as SVG circles and text labels, connected by curved paths generated with `d3.linkVertical()`. The visualization uses D3 v7 to compute the layout and bind data to SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fd0c10e64af44d80817c7a125c4619ca?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
