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

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 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 interactive family tree visualizes genealogical connections using a parent-child hierarchy. Built with D3.js v3, it renders the structure as an SVG diagram with rectangular nodes and labeled links, supporting zoom and drag interactions. The data from `family-data.json` is loaded via `d3.json()`, and the layout is computed using `d3.layout.tree()`. Node colors vary by type, and each node includes a link label with directional information.

Family Tree

This interactive family tree visualizes a multi-generational genealogy, with each family member displayed as a colored, labeled node in a hierarchical layout. The diagram is rendered as an SVG using D3.js v3’s tree layout, with links between relatives and a zoom-and-drag behavior for navigation. Each node’s color encodes a generation type, and hovering or clicking reveals tooltips and expands or collapses branches with a smooth animation. The data comes from a static JSON file, and the visualization updates dynamically as users interact.

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 visualization displays hierarchical relationships using a box-and-link diagram, with color-coded nodes representing different family member categories. Built with D3.js v3 and jQuery, the SVG-based tree supports zooming, dragging, and click interactions to explore the nested JSON data structure. The layout uses d3.layout.tree to position nodes, with animated transitions and tooltips that appear on hover, while custom utilities like breadthFirstTraversal handle collision detection and dynamic height calculation.

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.
