A family tree (genealogy) diagram renders hierarchical data from a JSON file (genealogy5.json) as an SVG. The visualization displays individuals as nodes connected by curved paths, with text labels indicating names and branch designations. The code uses D3.js v5's tree layout (`d3.layout.tree`) and diagonal path generator (`d3.svg.diagonal`) to position and draw the connections. Data transformation with `d3.nest()` restructures the flat JSON into a nested hierarchy before rendering nodes and links.

d3.tree - A Family Tree

This example visualizes a family tree as a static hierarchical diagram, showing genealogical relationships with names, birth and death years, and locations. The graph uses the d3.tree layout to position nodes, while d3.hierarchy structures the JSON data and provides descendant and link methods. Links are drawn as elbow paths with a custom function, and each node displays three text elements for the relative information. The visualization is rendered in SVG with a clean, readable design, demonstrating how d3.v4 handles tree layouts and nested data.

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

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 example shows an animated family tree built with D3.js, using a hierarchical layout to display generations from a root ancestor down to descendants. Each person appears as a labeled node connected by curved bézier links, with nodes expanding and collapsing on click. The visualization loads static JSON data and renders it as SVG, using the D3 tree layout, diagonal path generator, and transition animations to smoothly reveal branches as users interact.

Family Tree

A family tree visualization renders hierarchical relationships as an SVG diagram. Colored circles mark each person, with blue, yellow, and orange indicating their depth in the tree, while curved paths connect parents to children. The example uses D3 v5, but notably relies on the missing `d3.stratify` and `d3.tree` APIs, which are not part of the standard D3 library. The code manually positions nodes and links using the x and y coordinates from those undefined functions, with hard-coded data listing individuals and their parents.

Family tree using d3.js

This example displays a family tree as a node-link diagram rendered in SVG, with color-coded nodes indicating generational depth and curved paths connecting parents to children. The visualization uses d3.stratify() to structure flat parent-child data and d3.tree() to compute node positions within an 850x300 layout. Circles represent individuals labeled with names, while the code manually constructs cubic Bézier path strings for links and applies level-based fill colors via a custom getColor function.

Family tree - trial

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.

Tree

This example shows a simple hierarchical family tree with three generations, drawn in a bottom-to-top orientation using the D3.js v3 library. It demonstrates the `d3.layout.tree` layout and `d3.svg.diagonal` for rendering curved link paths, while nodes appear as circles with text labels for each person’s name. The data comes from a local `graph.json` file containing a nested “Father,” “Son,” and grandchildren structure. The SVG output is styled with minimal CSS, using a light gray border and black links, and the layout is positioned within a fixed margin and size.
