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.

Family Tree

This interactive family tree visualization displays hierarchical relationships using an expandable node-link diagram. The tree structure is defined in a JSON file with nodes representing family members and links depicting connections. Using D3.js v3, the visualization renders nodes as colored rectangles with descriptive labels, while animated transitions and zooming capabilities enhance navigation. Each node can be clicked to reveal or hide its children, and the layout automatically adjusts to accommodate the expanded structure. The tree is built using the `d3.layout.tree` algorithm, with SVG for rendering and CSS classes for styling node states like selected links and tooltips.

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

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 visualizes hierarchical relationships within a dataset, rendering nodes and links as SVG elements with smooth animations. The tree expands and collapses upon clicking individual nodes, with tooltips providing additional details. Built with D3.js v3 and React, it uses the `d3.layout.tree` algorithm to position nodes and applies custom CSS styles for color-coding based on node type, pulling data from the `family-data.json` file.

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 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 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.
