This example shows an interactive family tree built with D3.js, displaying a hierarchical dataset of names and parent-child relationships. The visualization uses the `d3.layout.tree` layout to position nodes and `d3.svg.diagonal` for the curved links between them. Each node is rendered as an SVG circle with a text label, and clicking on a node toggles its children, collapsing or expanding that branch. The nodes and links animate smoothly via transitions, with colors indicating different levels in the hierarchy.

Tree Example

This example shows an interactive family tree using a hierarchical node-link diagram, with each person represented as a colored circle and labeled with their name. The tree is built from a static JavaScript array and rendered with SVG, where nodes collapse and expand on click, and transitions animate position changes over 750 milliseconds. Using D3.js version 3’s `d3.layout.tree` and `d3.svg.diagonal`, the code computes the layout and draws curved links, while node fill and stroke colors encode the person’s type and level fields.

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.

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`.

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 example shows an interactive family tree using D3.js version 3. The visualization renders hierarchical data as a collapsible tree diagram, where clicking a node toggles its children. The code uses `d3.layout.tree` for layout, `d3.svg.diagonal` for curved links, and animated transitions via `transition()` with 750ms duration. Nodes are drawn as red-stroked circles with text labels, while links are green paths. The SVG output displays three generations of names, starting with Satyaveda as the root.

Tree Map

This example presents an interactive family tree diagram rendered with SVG and animated transitions. The visualization uses D3.js’s `d3.layout.tree` to compute hierarchical node positions and `d3.svg.diagonal` to draw curved links between generations. Nodes appear as red circles with blue outlines, labeled with names, and users can click any node to collapse or expand its children. The tree’s layout normalizes horizontal spacing by depth, while entering and exiting elements animate smoothly via `transition` methods over a 750-millisecond duration. The data is a hardcoded array representing three generations of a family lineage.

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 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.
