This example presents an interactive collapsible tree visualization built with React and D3.js v6. Clicking a node re-roots the hierarchy to that node, toggling its children open or closed while animating transitions between states. The SVG rendering uses `d3.tree`, `d3.hierarchy`, and `transition.attrTween` to smoothly update node positions and link paths over 250-millisecond durations. A pop-up div displays the clicked node’s ID and name, positioned dynamically within the viewport.

Collapsible Tree Hierarchy

This example shows an interactive collapsible tree hierarchy, allowing users to click on nodes to expand or collapse their children, and to navigate the tree by re-rooting it at a clicked node. The visualization uses D3.js v6 to compute a tidy tree layout with `d3.hierarchy` and renders it as an SVG, with animated transitions for all changes. A custom node-info div displays the name and ID of the last clicked node. The code also manages a stack to remember previous roots, enabling backward navigation through the hierarchy.

Collapsible Tree Hierarchy Reformatted - Real Data

This interactive collapsible tree visualization displays hierarchical data as an SVG with animated transitions between expanded and collapsed states. Users click nodes to re-root the tree and reveal child nodes, while a dynamic info panel shows the selected node’s ID and name. Built with d3.v6 and React, it uses the `transition()` API for smooth resizing and layout updates, with node positions computed via `root.descendants()` and `root.links()`. The rendering relies on SVG elements, including circles and text, styled with CSS. The dataset originates from a real source, as indicated in the example’s metadata.

Collapsible Tree Restructured

This example shows an interactive collapsible tree diagram built with D3.js v6 in a React framework. Clicking a node toggles its children and displays a floating info panel with the node's ID, name, and value. The visualization uses SVG rendering with animated transitions via `d3.transition` and a hierarchical layout from `d3.tree`. Node and link enter/update/exit patterns handle dynamic restructuring, with `d3.select` managing the DOM and event listeners for user interaction.

Collapsible Tree

This interactive visualization displays a hierarchical tree structure, allowing users to click on nodes to expand or collapse their child branches. The tree’s layout dynamically repositions nodes with animated transitions, adjusting the SVG canvas height to fit the visible structure. Built with React and D3 v6, it uses the `d3.tree()` layout, `d3.linkHorizontal()` for connecting links, and reads hierarchical JSON data from a remote file. Node labels are rendered alongside circular markers, with parent and leaf nodes shown in different colors.

Collapsible Tree Hierarchy - Real Data - Structured

This example presents a collapsible tree hierarchy using real data, rendered as an SVG. The visualization displays nodes that can be clicked to expand or collapse their children, revealing the structured relationships in the data. Built with React and D3 v6, it uses `d3.hierarchy` to process the data and `d3.tree` for layout, with custom JavaScript handling node clicks and updating the tree structure dynamically through `updateTree`.

Collapsible Tree Hierarchy - Real Data

A collapsible tree hierarchy displays real hierarchical data, with nodes that expand and collapse on click. It also enables navigation by re-rooting the tree view to the clicked node, while a stack tracks the path back to previous roots. The visualization uses d3.v6’s tree layout and transitions, rendering SVG circles and text labels with animated updates. A node-info div shows details for the selected item, and the canvas height dynamically adjusts to fit the visible hierarchy.

Collapsible Tree New Tree Each Time

This example demonstrates a collapsible tree diagram where each click on a node generates a fresh tree layout. It uses d3.hierarchy and d3.tree to compute the node positions, with d3.transition to animate the expanding and collapsing of branches. The visualization updates the SVG elements dynamically, reassigning parent-child relationships and rebuilding the tree structure on each interaction. Data is derived from a hardcoded hierarchical JSON object, rendered as colored circles and connecting links.

Collapsible Tree Example

This interactive visualization displays a collapsible tree diagram using d3.layout.tree, with nodes rendered as SVG symbols (circles, crosses, or diamonds) and links colored by a level property from the embedded JSON data. The code loads d3 v3 from a CDN and uses d3.svg.diagonal for curved edges, along with d3.svg.symbol to vary node shapes based on value thresholds. The tree includes hardcoded family hierarchy data, with fixed node depths and margin-based layout, though no collapse/expand behavior is implemented in the shown script.
