Forked from ICE - 8: Tree Map

This example presents an interactive family tree diagram rendered with SVG and animated transitions. The visualization uses D3.js’s `d3.layout.tree` to compute hierarchical node positions and `d3.svg.diagonal` to draw curved links between generations. Nodes appear as red circles with blue outlines, labeled with names, and users can click any node to collapse or expand its children. The tree’s layout normalizes horizontal spacing by depth, while entering and exiting elements animate smoothly via `transition` methods over a 750-millisecond duration. The data is a hardcoded array representing three generations of a family lineage.

Tree Example

This example shows an interactive family tree built with D3.js, displaying a hierarchical dataset of names and parent-child relationships. The visualization uses the `d3.layout.tree` layout to position nodes and `d3.svg.diagonal` for the curved links between them. Each node is rendered as an SVG circle with a text label, and clicking on a node toggles its children, collapsing or expanding that branch. The nodes and links animate smoothly via transitions, with colors indicating different levels in the hierarchy.

Tree Example

This example shows an interactive family tree using a hierarchical node-link diagram, with each person represented as a colored circle and labeled with their name. The tree is built from a static JavaScript array and rendered with SVG, where nodes collapse and expand on click, and transitions animate position changes over 750 milliseconds. Using D3.js version 3’s `d3.layout.tree` and `d3.svg.diagonal`, the code computes the layout and draws curved links, while node fill and stroke colors encode the person’s type and level fields.

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 family tree visualizes a multi-generational genealogy dataset using a collapsible tree layout. Users can click on nodes to expand or collapse branches, with smooth animated transitions between states. The visualization is built with React and D3.js, specifically using `d3.layout.tree` for hierarchical positioning and `d3.svg.diagonal` for curved links. SVG elements render nodes and text labels, while CSS styles define the red node circles and blue connecting lines. The tree data is embedded directly in the JavaScript, and the animation duration is set to 750 milliseconds.

Family Tree

This example shows a family tree visualization with nodes colored by generation and animated SVG paths connecting parents to children. The tree layout uses d3.stratify() and d3.tree() to compute node positions from the hierarchical data. Circles and text labels are rendered as SVG elements, with d3 transitions animating the connecting paths and node sizing. Generation colors are assigned via a custom switch function, and the SVG fills the browser viewport.

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.

Tree Example

This example shows an interactive family tree using D3.js version 3. The visualization renders hierarchical data as a collapsible tree diagram, where clicking a node toggles its children. The code uses `d3.layout.tree` for layout, `d3.svg.diagonal` for curved links, and animated transitions via `transition()` with 750ms duration. Nodes are drawn as red-stroked circles with text labels, while links are green paths. The SVG output displays three generations of names, starting with Satyaveda as the root.

Tree map

A hierarchical tree map visualizes a family tree of names, rendered as collapsible nodes linked by curved paths. Clicking a node toggles its children, with animated transitions using d3.layout.tree, d3.svg.diagonal, and SVG circle and text elements. The data is a hardcoded JavaScript array of nested objects. Node positions shift horizontally by depth, and all updates animate over 750 milliseconds using D3’s transition methods, with styling for links and node circles defined in CSS.
