This example shows an interactive zoomable and pannable tree diagram that visualizes the hierarchical structure of the flare JSON dataset. The visualization supports drag-and-drop repositioning of nodes, with ghost circle indicators and animated path updates during the operation. Built with D3 v3, it uses `d3.layout.tree`, `d3.svg.diagonal`, and `d3.behavior.zoom` to render SVG nodes and links. The diagram automatically sorts nodes alphabetically and includes panning near the viewport edges while dragging.

Untitled

An interactive drag-and-drop tree diagram visualizes the hierarchical structure of the Flare JSON dataset. The visualization uses D3.js v3 to render nodes and links as SVG elements, and incorporates an animation system with a zoom listener and pan controls. The tree layout is computed using `d3.layout.tree` and `d3.svg.diagonal` projections, while node dragging and sorting are handled through custom JavaScript functions. The interface allows users to explore the dataset by repositioning nodes within the tree.

Tree

An interactive tree visualization displays a hierarchical dataset from flare.json, with collapsible nodes, color-coded status indicators, and breadcrumb navigation. The right panel shows user and token details for selected nodes. Implemented with React and D3 v3, it uses `d3.layout.tree`, `d3.svg.diagonal`, and `d3.behavior.zoom` for pan/zoom, with SVG rendering and animated transitions. Node colors reflect time-based status, and blinking effects highlight urgent items, while the interface supports expanding or collapsing all branches.

Untitled

This example demonstrates an interactive, zoomable tree diagram built with D3.js, presenting hierarchical data from a JSON file. Users can pan and zoom the tree, as well as drag and drop nodes to rearrange them, with animations using `d3.layout.tree` and `d3.svg.diagonal`. The code includes custom panning logic and a zoom listener with scale constraints, rendering the visualization as SVG elements with linked paths and draggable node circles.

Collapsible Tree

This interactive visualization displays a collapsible hierarchical tree of the Flare software package’s class structure. Users click nodes to expand or collapse branches, with smooth transitions animating the tree’s layout changes. The visualization uses d3.hierarchy and d3.tree to compute node positions, d3.linkHorizontal for curved links, and d3.zoom for panning and scaling. Data comes from flare-2.json, rendered as SVG elements with circles and labels, updating via enter, update, and exit selections with d3.transition.

Untitled

This interactive tree diagram visualizes the hierarchical structure of the flare codebase, with each node representing a class or category and its size indicating relative importance. Users can expand and collapse branches, zoom and pan the view, and rearrange nodes by dragging them to new positions within the hierarchy. The visualization is built with D3.js version 3, using the tree layout, SVG rendering, and a custom drag-and-drop implementation that temporarily removes and reattaches nodes. Data comes from the bundled flare.json file, and the interface supports smooth animated transitions between states.

Test

This example shows a hierarchical dataset of the Flare visualization library, organized as a tree with branches for analytics, animation, data, and display. Animated transitions smoothly rearrange the nodes when the tree is toggled between layouts. The visualization uses D3.js version 3 with SVG rendering and animation, relying on the force-directed layout algorithm from d3.js to position the connected nodes. The data is provided as a static JavaScript object, and the interaction reveals structural relationships through size and grouping.

Tree

This interactive tree diagram visualizes a hierarchical dataset, displaying nodes as colored boxes connected by labeled links with directional arrows. The layout renders synchronously in SVG and supports zooming and dragging via `d3.behavior.zoom`. Node colors map to `type` fields, and tooltips appear on hover, while link direction (SYNC or ASYN) is shown through arrow markers. Data loads from JSON using `d3.json`, and the layout uses `d3.layout.tree` with a `breadthFirstTraversal` to adjust SVG dimensions dynamically.

D3 Tutorial

This example demonstrates a tree visualization using the Flare dataset, displayed as a circular layout with labeled nodes and hierarchical branches rendered in SVG. The code uses D3 v5’s `d3.hierarchy` and `d3.tree` to compute node positions, then draws links and circles with `d3.select` and SVG elements. The hierarchical structure shows parent-child relationships across categories like analytics, animate, and physics, with each leaf node’s value represented by its visual placement. The visualization is contained within a fixed 960x500 viewport.
