Forked from Family tree

This family tree visualization displays a hierarchical genealogy with names and birth years, using a horizontal tree layout where each node represents a family member and links show parent-child relationships. The example builds an interactive SVG graphic using D3 v5 APIs including `d3.tree`, `d3.hierarchy`, `d3.linkHorizontal`, and `d3.zoom`. It loads family data from an external JSON file, with text labels whose font size decreases at deeper levels. The visualization supports panning and zooming through the zoom behavior, while ancestor nodes are centered and descendants are left-aligned.

Family Tree

This interactive family tree displays hierarchical relationships across multiple generations, with each node labeled by name and colored according to its position in the lineage. The visualization uses D3 v5’s `tree` layout to compute node positions and `linkHorizontal` to draw curved connecting paths, while the `zoom` function enables panning and scaling of the SVG canvas. The included JSON data file provides the family structure, and the code explicitly assigns font sizes based on tree depth and text colors from the data attributes.

Family Tree

This interactive family tree visualization displays a hierarchical dataset of names, with each node colored according to its position and labeled with a person's name. The tree uses a left-to-right layout, where the depth of each node is reflected in the font size, making generational levels visually distinct. The visualization is built with D3 v5, employing the `tree`, `hierarchy`, and `linkHorizontal` APIs to compute the layout and draw connecting paths. All elements are rendered as SVG, with node labels and colors driven directly from the `data.json` file, and the entire graphic supports zooming via D3's `zoom` event.

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

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 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 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.
