This example shows an interactive tree diagram with collapsible nodes, where clicking a node expands or collapses its children, and hovering reveals a temporary “More info” label. The visualization uses the D3.js v3 layout `d3.layout.tree` to position nodes and `d3.svg.diagonal` to draw curved link paths, rendered as SVG. Animated transitions update node positions via `transition().duration()`, while the dataset is a small hardcoded hierarchy with a single top parent and nested descendants. Mouseover events trigger text appending and removal directly on SVG groups.

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.

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

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 example shows a collapsible hierarchical tree diagram using D3 v3. Nodes representing a small family dataset appear as white circles with steelblue outlines, connected by curved gray links, and labeled with names. Clicking a node toggles its children, animating the tree’s layout transitions over 750 milliseconds. The code uses `d3.layout.tree`, `d3.svg.diagonal`, and SVG-based rendering, with enter, update, and exit selections to handle dynamic node and link changes.

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 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 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 an interactive tree diagram built with D3.js, where clicking a node collapses or expands its children with smooth animated transitions. The data is a hardcoded JSON structure representing a family hierarchy, with names like Roshan and Nimmat. The code uses `d3.layout.tree` to compute node positions and `d3.svg.diagonal` to draw curved links between parent and child nodes. Node and link elements are rendered as SVG circles, text, and paths, with transitions handled by D3's `transition` API.
