Forked from Tree 7

This example presents an interactive collapsible tree diagram built with D3.js v3, visualizing a hierarchical dataset of cardiology departments and patient information. The tree layout uses SVG rendering and animation to smoothly transition nodes and links when users click to expand or collapse branches. The visualization employs the `d3.layout.tree` function to compute node positions and `d3.svg.diagonal` for link paths, with data loaded from a JSON file.

Tree 7

This example shows an interactive tree diagram of hospital departments, with nodes labeled by location or clinic name (e.g., KFSH, Riyad, Dental). Clicking a node collapses or expands its children with a smooth animated transition. The visualization uses D3 v3’s `d3.layout.tree` to compute node positions and `d3.svg.diagonal` for curved link paths. Data is loaded from an external JSON file, and SVG elements are updated via D3’s enter/update/exit pattern with a 1100-millisecond duration.

Tree 7

Animated tree diagram that shows a branching dataset from a JSON file, where nodes represent hospital divisions and clinics, and specific clinic nodes with blinking red or blue highlights flag elevated service counts or warnings. Built with D3.js, it uses a tree layout with collapsible nodes and smooth transitions to rearrange the visualization on click. Node styling uses CSS keyframe animations for the warning indicators, and all rendering is handled by inline SVG.

Tree Example

This interactive tree diagram displays hierarchical data with collapsible nodes. The visualization uses the D3.js library (version 3.5.17) with a static JSON dataset containing a root node and its descendants. The code employs `d3.layout.tree` for layout computation and `d3.svg.diagonal` for link rendering. Users can click nodes to expand or collapse subtrees, triggering smooth animated transitions via D3's `.transition()` method. The SVG rendering includes styled circles and text labels, with nodes colored steelblue or lightsteelblue depending on collapsed state.

Tree 7

This interactive tree diagram visualizes hierarchical data from a JSON file, using a node-link layout to show the structure of a medical facility's departments and services. The visualization is built with D3 v4, using the `d3.hierarchy` function to process the tree data and SVG for rendering. Users can interact with the diagram by dragging nodes to reorganize the tree, panning across the view, and zooming, with animations supporting these interactions.

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.

Tree Example

This tree diagram shows a hierarchical dataset with collapsible nodes, where clicking a parent node hides or reveals its children with animated transitions. The visualization uses D3.js v3’s `d3.layout.tree` to compute node positions and `d3.svg.diagonal` for curved links, rendered as SVG elements. Node and link styling are defined via CSS classes, and the `update` function handles enter, update, and exit transitions with a 750ms duration. The static sample data includes a top-level node with two second-level branches, demonstrating the interactive expand/collapse behavior.

Fork of Fork of Fork of Tree 7

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.

Collapsible tree diagram in v7

This interactive tree diagram displays hierarchical data using D3 v7’s `d3.tree` layout, rendering parent-child relationships as linked circles and text labels. Clicking any parent node collapses its descendants, with smooth 750ms transitions animating the nodes and links to the clicked node’s position; clicking again expands the subtree. The SVG uses a simple dataset of labeled levels, and the code applies `d3.hierarchy` for data structuring and the `diagonal` path generator for curved links.
