This example presents a collapsible node-link tree diagram that visualizes a small hierarchical dataset from a JSON file. The visualization loads the JSON data and displays it as an interactive tree, where users can click on nodes with children to expand or collapse branches. The tree layout is computed using `d3.layout.tree` and rendered as an SVG graphic, with nodes drawn as circles and connections as diagonal path links. The visualization uses the `qn_tree.json` data source, and all transitions between expanded and collapsed states are animated with D3's `.transition()` method.

Fork of Tree 7

This interactive tree diagram visualizes a hierarchical dataset loaded from a JSON file, using a collapsible node layout. The visualization employs D3.js version 3.5.17, specifically `d3.layout.tree` for tree layout and `d3.svg.diagonal` for curved link paths. Nodes are rendered as circles with text labels, and clicking a node toggles its children, triggering a smooth 1100ms transition animation that repositions nodes and links. The SVG-based rendering supports interactive exploration of the nested family-tree-like structure.

A clickable, animated tree diagram shows hierarchical data loaded from a local JSON file. Clicking a node toggles its children, collapsing or expanding subtrees with smooth transitions. The visualization uses D3 v3’s `d3.layout.tree` to calculate node positions and `d3.svg.diagonal` to draw curved links, while SVG circles and text labels update via `transition()` over 1100 milliseconds. Node fill colors distinguish collapsed branches from open ones.

This example shows an animated, collapsible tree diagram built with D3.js v3, displaying hierarchical data loaded from a JSON file. The tree layout positions nodes by depth, and clicking a node toggles its children in or out with smooth transitions. The visualization uses `d3.layout.tree`, `d3.svg.diagonal` for curved links, and SVG elements for circles and text labels. Node and link styling uses pink circles and gray paths, with all interactions handled by a click function that updates the layout.

This interactive tree diagram visualizes the hierarchical relationships in a small JSON dataset (qn_tree.json), starting from a root node and branching through named individuals like Ganne, sai, and bindu. Nodes expand and collapse on click, with smooth animated transitions of curved links and repositioned labels. The implementation uses D3 v3’s `d3.layout.tree`, `d3.svg.diagonal`, and standard SVG transitions to update positions over a duration of 1100 milliseconds, while circles and text change styling based on collapsed state.

This example presents an animated, interactive tree diagram built with D3.js. It visualizes a small hierarchical JSON dataset starting from a root node, with branches expanding three levels deep. Users can click any node to collapse or expand its children, triggering smooth transitions of the SVG paths and circles. The layout uses `d3.layout.tree` and `d3.svg.diagonal` for the curved links, with nodes repositioned over a fixed horizontal depth. The rendering relies on SVG elements and timed transitions via `.transition()` with a set duration.

This collapsible tree diagram visualizes a small hierarchical dataset loaded from a JSON file, with nodes labeled by names such as “kamasani” and “lalli.” Users can click any node to expand or collapse its children, triggering smooth animated transitions of both the node positions and the connecting diagonal links. The implementation uses D3 v3’s `d3.layout.tree`, `d3.svg.diagonal`, and SVG transitions with a duration of 1100 milliseconds. Nodes are rendered as green-stroked circles with bold text, and the tree layout spreads vertically by depth, with each level offset by 180 pixels.

This interactive tree diagram displays a hierarchical dataset of names, with nodes that can be clicked to expand or collapse their child branches. The visualization uses D3.js version 3.5.17, employing the `d3.layout.tree` API to compute node positions and `d3.svg.diagonal` to draw curved links between parent and child nodes. Nodes transition smoothly over 1100 milliseconds using D3's `.transition()` method, while SVG circles and text labels represent each entry. The data comes from a local JSON file loaded via `d3.json`, and the entire graphic is rendered as an animated SVG.
