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.

AI-generated description

This is a d3.js tree diagram that incldes an interactive element as used as an example in the book D3 Tips and Tricks.

Any parent node can be clicked on to collapse the portion of the tree below it, on itself. Conversly, it can be clicked on again to regrow.

It is derived from the Mike Bostock Collapsible tree example but it is a slightly cut down version.

Tree Example

This interactive tree diagram displays a hierarchical dataset with a single root node and two levels of children. Clicking any parent node collapses its subtree, and clicking again expands it. The visualization is built with D3.js version 3.5.17, using `d3.layout.tree` and `d3.svg.diagonal` to compute and draw the layout as SVG elements. Animated transitions, controlled by `node.transition` and a 750-millisecond duration, smoothly move nodes and links between states. The example is adapted from Mike Bostock’s collapsible tree and uses hardcoded JavaScript data.

Tree Example

This example displays an animated, collapsible tree diagram representing a three-level family hierarchy, with nodes showing names and links connecting parents to children. Clicking a node toggles the visibility of its subtree, smoothly transitioning the layout as branches expand and collapse. Built with D3.js version 3.5.17, the visualization uses the `d3.layout.tree` and `d3.svg.diagonal` APIs to compute the node positions and draw curved link paths, while SVG transitions animate the changes over 750 milliseconds. The data is hardcoded as a nested JavaScript array in the HTML file.

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 Example

This interactive tree diagram displays the hierarchical structure of a dataset, with nodes and links rendered using SVG and animated transitions. The visualization uses D3.js version 3, with the `d3.layout.tree` for layout and `d3.svg.diagonal` for curved links. Clicking nodes expands or collapses their children, with smooth transitions achieved through `transition.attr`. The static data is embedded in the code, and the example also includes a separate CSV file for population data, though it is not referenced in the visualization.

Tree Example

This example shows a collapsible tree diagram built with D3.js, displaying hierarchical data with nodes for “Grand parent,” “Parent A,” and “Parent B.” Clicking a node toggles its children, animating the layout transitions over 750 milliseconds. The visualization uses `d3.layout.tree` for positioning, `d3.svg.diagonal` for curved links, and SVG circles and text for nodes. Data is hardcoded in a JavaScript array, rendered with React-style CSS classes and pointer cursor interactions.

Tree Example

An interactive, animated tree diagram displays a static, hierarchical dataset of nodes with names and sizes, such as “node 10” and “root.” Users click nodes to expand or collapse their children, with smooth transitions repositioning nodes and links over 750 milliseconds. Built with D3.js, the example uses `d3.layout.tree`, `d3.svg.diagonal`, and SVG transitions to render the structure, styling circles and paths via CSS. Data is hardcoded in JavaScript, and rendering uses SVG with animation.

Tree Example

This interactive tree diagram visualizes a hierarchical dataset, displaying parent-child relationships through collapsible nodes. The visualization uses D3.js v6, with the entire structure rendered as SVG elements. The tree layout is calculated using `d3.tree()` and links are drawn as horizontal curves using `d3.linkHorizontal()`. Users can click on any node to remove it from the tree, and the layout dynamically updates accordingly. The example also defines an unused `insert` function, suggesting potential for adding new nodes, though this behavior is not implemented in the current code.

Tree Example

An interactive tree diagram displays hierarchical data with collapsible nodes, marking leaf nodes and internal nodes distinctly with text labels. Clicking a node toggles its child branches, with animated transitions repositioning nodes and links. The visualization uses D3.js 3.5.17, SVG rendering, and React via the VizHub framework, building the tree via `d3.layout.tree` and drawing curved diagonal links with `d3.svg.diagonal`.
