{"version":"1.0","type":"rich","title":"Operation Tree","description":"This example shows a collapsible operation tree for electric vehicle modes, with color-coded nodes distinguishing normal and fault operation modes alongside their sub-modes. Users can click nodes to expand or collapse child branches, triggering animated transitions as nodes reposition. Built with D3 v5, the visualization uses `d3.tree` and `d3.hierarchy` for layout and `d3.linkHorizontal` for curved links, while `d3.zoom` enables panning and zooming. Nodes are rendered as SVG rectangles with labels, and data comes from a static JavaScript object defining the hierarchical structure.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4ef86bf3409d42ff94a3e0d327198298?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
