This interactive family tree visualization in D3.js v3 displays hierarchical relationships among named individuals, with expandable and collapsible nodes. Clicking a node toggles its children, animating the tree’s layout with smooth transitions. The SVG-based chart uses `d3.layout.tree` for positioning and `d3.svg.diagonal` for curved links. Built with React, it renders circular nodes with labels and color-coded states, animating position changes via `transition` over 750 milliseconds.

Family Tree

This interactive family tree visualization displays hierarchical relationships using an expandable node-link diagram. The tree structure is defined in a JSON file with nodes representing family members and links depicting connections. Using D3.js v3, the visualization renders nodes as colored rectangles with descriptive labels, while animated transitions and zooming capabilities enhance navigation. Each node can be clicked to reveal or hide its children, and the layout automatically adjusts to accommodate the expanded structure. The tree is built using the `d3.layout.tree` algorithm, with SVG for rendering and CSS classes for styling node states like selected links and tooltips.

Family Tree

This interactive family tree visualizes hierarchical relationships using D3.js’s tree layout, with nodes as white circles connected by gray links. Users can click a node to collapse or expand its children, and double-click a node’s label to edit names in place via a foreignObject input. The rendering uses SVG paths with smooth `transition` animations for node and link repositioning. Zooming is enabled through `d3.zoom`, scaling the entire diagram between 0.1× and 10×. The code defines the tree structure with `d3.hierarchy` and `d3.tree`, and updates positions dynamically during interactions.

Family Tree

This interactive family tree visualizes hierarchical relationships within a dataset, rendering nodes and links as SVG elements with smooth animations. The tree expands and collapses upon clicking individual nodes, with tooltips providing additional details. Built with D3.js v3 and React, it uses the `d3.layout.tree` algorithm to position nodes and applies custom CSS styles for color-coding based on node type, pulling data from the `family-data.json` file.

Family Tree

This example presents an interactive family tree visualization showing hierarchical relationships among named individuals. The tree layout uses D3’s `d3.layout.tree` with SVG rendering and animated transitions. Nodes are color-coded by type and include click-to-expand/collapse behavior, with tooltips and zoom/drag navigation via `d3.behavior.zoom`. The tree structure comes from external JSON data loaded with `d3.json`, and the visualization is built within a React wrapper using D3 v3 and jQuery.

Family Tree

This visualization presents a family tree as an animated, zoomable node-link diagram. It reads hierarchical data from a JSON file and renders it as colored, clickable rectangles connected by labeled links, using D3.js v3 and React. The layout, computed via `d3.layout.tree`, supports interactive expansion and collapse of nodes, with tooltips and drag-to-pan functionality. The tree's size adjusts dynamically based on the data, and the code includes custom SVG definitions for arrows and drop shadows.

Family Tree

This visualization presents a family tree as an interactive, animated SVG diagram built with React and D3.v3, using the `d3.layout.tree` API to compute the hierarchical layout. Color-coded nodes (distinguished by `type` values) represent different family members, and red links with directional arrows show parent-child relationships. Users can click nodes and zoom the entire tree via a zoom behavior. Data is loaded asynchronously from the `family-data.json` source, and the tree dynamically resizes its SVG canvas based on the maximum depth and breadth of the loaded data.

Family Tree

This interactive family tree visualizes a multi-generational genealogy dataset using a collapsible tree layout. Users can click on nodes to expand or collapse branches, with smooth animated transitions between states. The visualization is built with React and D3.js, specifically using `d3.layout.tree` for hierarchical positioning and `d3.svg.diagonal` for curved links. SVG elements render nodes and text labels, while CSS styles define the red node circles and blue connecting lines. The tree data is embedded directly in the JavaScript, and the animation duration is set to 750 milliseconds.

Family Tree

This interactive family tree uses a static dataset of parent-child relationships to display three generations of a family. The visualization uses D3.js v6 and React, rendering circles as nodes connected by animated lines in an SVG. The tree layout is computed using D3's stratify and tree algorithms, with the nodes and links animating into place via transitions that vary in duration based on node depth. The data is hardcoded in the source file, and each node displays the family member's name.
