This example shows an interactive family tree visualization built with D3.js, displaying hierarchical relationships among family members using a collapsible tree layout rendered as SVG. The visualization loads JSON data containing the family structure and renders each person as a colored, clickable node connected by labeled links, with names and relationships displayed inline. Using D3 v3’s tree layout, the code dynamically computes node positions, applies zoom and drag behavior via `d3.behavior.zoom`, and animates node expansions and collapses with `transition.attrTween`. Tooltips appear on hover, and the tree supports mouse-wheel zoom and panning for exploration.

family tree

This interactive family tree visualization displays hierarchical relationships using collapsible nodes and animated transitions. Built with D3.js and jQuery, it renders an SVG tree with color-coded node types (blue, green, yellow, purple) and directional links labeled as SYNC or ASYN. The layout computes node positions dynamically via D3’s tree layout, with zooming, dragging, and tooltip support. Data comes from a local JSON file, and the tree adapts its dimensions to the maximum breadth and depth of the hierarchy during traversal.

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

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

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 family tree visualization displays hierarchical relationships among family members using a collapsible tree layout. The D3.js v3 library constructs the diagram as SVG elements, with nodes represented as colored rectangles that branch from a root ancestor. The tree loads its structure from a JSON data file, and users can click individual nodes to expand or collapse their branches. The visualization includes zoom and pan capabilities through D3's behavior API, while a custom tooltip system displays additional information on hover.

Family 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

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 example presents an interactive family tree visualization rendered as a collapsible hierarchy of boxes and links. It demonstrates how D3.js v3, jQuery, and local ES6 modules work together to load data from a JSON file and display it as an SVG tree. The code uses D3’s tree layout, zoom and drag behavior, and custom arrow definitions to show parent-child relationships. Node colors vary by type, and the layout dynamically adjusts its size based on the tree’s depth and width.
