An interactive collapsible tree visualization displays the Flare dataset hierarchy, with nodes and links rendered as SVG elements. The graph supports dynamic restructuring through user interactions: shift-clicking appends new child nodes, while alt-clicking triggers name editing. The layout recalculates node positions with smooth transitions using D3 v5's hierarchy layout and transition APIs, including `root.descendants()`, `root.links()`, and `linkHorizontal()`. Node colors shift based on collapsed states, and the `update` function handles enter, update, and exit selections for both nodes and paths.

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.

Collapsible Tree Version 1

This interactive visualization displays a hierarchical tree of the Flare software package’s classes, rendered as collapsible nodes with animated transitions. Built with D3 v6, it uses `d3.tree()` for layout, `d3.linkHorizontal()` for edges, and SVG elements for rendering. Clicking a node toggles its children, with the view zoomable via d3.zoom. The underlying data comes from the `flare-2.json` file, and node labels use a white stroke halo for readability.

Collapsible Tree

This interactive collapsible tree visualizes the hierarchical structure of the Flare dataset, displaying nodes as circles connected by curved links. Users can click any node to expand or collapse its subtree, with smooth 750-millisecond transitions animating nodes and links between positions. The visualization uses D3 v3's `d3.layout.tree` to compute positions, `d3.svg.diagonal` for link paths, and SVG transitions to update the scene. Node colors change from white to lightsteelblue when children are hidden, and the root collapses all branches initially. Text labels position dynamically based on whether a node has visible or hidden children.

Hello VizHub

This example shows an interactive dendrogram layout of a hierarchical data structure, rendered as SVG circles connected by curved paths. Users can click nodes to inspect them, press Shift-click to add random "florps" children, or Cmd-click to delete entire subtrees, triggering re-renders that change link and node colors. The code relies on d3.hierarchy, d3.cluster, d3.zoom, and the d3 v5 event handling, with data defined as a plain JavaScript object and layout computed at 500x900 pixels.

Collapsible Tree Version 1

This interactive collapsible tree visualizes the hierarchical structure of the Flare dataset. Users can click on any node to expand or collapse its children, revealing the nested organization of the data. The visualization uses D3.js v6 to compute the tree layout and renders nodes and links as SVG elements. Transitions between states are animated, and the view automatically adjusts to fit the visible portion of the tree. The hierarchical data is loaded from an external JSON file, and the layout dynamically recalculates as the tree structure changes.

Fork of Collapsible Tree Version 1

This interactive collapsible tree visualization displays a hierarchical dataset of the Flare visualization library codebase, with nodes representing packages and functions. Built with D3 v6, it renders as an SVG with animated transitions that reposition nodes and links when a node is clicked to expand or collapse its children, using a horizontal diagonal link layout. The implementation relies on `d3.tree()` for layout, `d3.linkHorizontal()` for edges, `d3.select()` for SVG manipulation, and `d3.transition()` for smooth 250ms animations. The tree data comes from the `flare-2.json` file, and nodes with names shorter than seven characters are initially collapsed.

Fork of Collapsible Tree Version 1

This visualization shows a collapsible tree of the Flare software package hierarchy, where nodes with children can be clicked to expand or collapse their subtrees with animated transitions. Built with D3 v6, it uses `d3.tree()` and `d3.linkHorizontal()` to compute and draw the layout as SVG paths and circles. Zooming is enabled via `d3.zoom()`, and clicking toggles child visibility while the viewBox animates to fit the visible nodes. Data comes from the flare-2.json file, which encodes the package structure.

Hierarchical List

This example visualizes a hierarchical dataset as an animated, collapsible tree, showing parent-child relationships across multiple levels of the Flare library’s structure. It uses D3.js v5 with SVG rendering, employing the `d3.hierarchy()` layout to compute node positions and `d3.tree()` to arrange them. The visualization draws curved link paths (`d3.linkHorizontal()`) and circular node markers, with text labels for each element. A smooth transition animates the tree’s expansion and collapse when a node is clicked, using `transition.duration()` and `transition.attr()` to update positions. The data is embedded as a JavaScript object in the code, with leaf nodes carrying a `size` attribute.
