Forked from Interactive Tree

A D3.js v5 family tree visualizes hierarchical relationships with colored nodes and horizontal links, using SVG rendering and animated transitions. The tree layout (`d3.tree`) positions nodes, while `d3.hierarchy` converts the JSON data from `data.js` into a traversable structure. Users can click nodes to collapse or expand branches, triggering smooth animations via `transition()`. Zoom and pan functionality is implemented with `d3.zoom`, and drag gestures are detected on node groups. Node colors derive from the data object, and labels display names with dynamic sizing based on text length.

Family Tree

A family tree visualization renders hierarchical relationships from a JSON data structure. The D3.js v3 layout algorithm positions nodes in a tree layout, with each family member displayed as a colored rectangle containing their name. Clicking a node collapses or expands its children, triggering smooth animated transitions. The visualization uses SVG elements, D3's `d3.layout.tree()`, and `d3.behavior.zoom()` for panning and zooming, with jQuery handling interactions and tooltips that appear on hover.

Family Tree

This interactive D3.js v3 family tree visualizes hierarchical generational data from a JSON file, using colored nodes to distinguish four family types. The tree layout computes node positions, with SVG rectangles and foreignObject text blocks rendering each family member’s name. Animation transitions reposition nodes when the hierarchy updates, while zoom and drag behaviors allow panning and scaling via `d3.behavior.zoom`. Links and arrow markers connect parent-child relationships, and a collision-avoidance pass prevents overlapping nodes.

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 visualization displays hierarchical relationships among individuals, with nodes color-coded by type and labeled links showing connections. The tree supports zooming, panning, and clicking nodes to expand or collapse branches. Built with d3.v3, it uses `d3.layout.tree` for layout, SVG elements for rendering, `d3.behavior.zoom` for interaction, and animated transitions. Data comes from a JSON file containing nested family members and their link attributes.

Family Tree

This interactive family tree visualizes hierarchical relationships using a collapsible node layout. The D3.js v3 code loads JSON data and renders individuals as colored rectangles connected by directional links, with tooltips and zooming support. The tree uses `d3.layout.tree` for positioning, SVG for rendering, and CSS for styling nodes and links. Animated transitions handle node expansion and collapse when clicked, while arrow markers indicate link direction.

Family Tree

A family tree visualization displays hierarchical parent-child relationships across four generations, with nodes colored by depth and labeled with character names. Each connection animates from a horizontal line into a diagonal link as the tree expands. The implementation uses D3 v6’s `d3.stratify()` to build the hierarchy from flat data and `d3.tree()` to compute layout positions, while SVG circles, text, and paths are rendered with transitions on `attr` for smooth node growth and link drawing.

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.
