This example displays a family tree as an interactive hierarchical diagram using D3.js v3. The tree layout organizes nodes by generation, with each family member represented as a colored rectangle and labeled with their name. SVG elements render the nodes and links, while the data comes from a JSON file containing nested parent-child relationships. Clicking on nodes triggers zooming and dragging behavior via d3.behavior.zoom, and hovering reveals tooltips. The code employs d3.layout.tree for positioning and applies custom collision detection to prevent overlapping nodes.

ICE-8 (Family Tree)

This example shows an interactive family tree visualization built with D3.js (v3) and SVG. It renders hierarchical data from a JSON file as colored, rounded rectangles connected by links, with each node color-coded by generation type. The tree layout uses d3.layout.tree, and users can click nodes to expand or collapse branches. The visualization includes zoom and drag behavior via d3.behavior.zoom, along with tooltips and drop-shadow filters for visual polish.

ICE-8_Family_Tree

This example shows an animated family tree visualization built with D3.js version 3. The tree uses an SVG layout with rectangular nodes color-coded by type, and it renders parent–child relationships from a JSON data source. The visualization supports interactive node clicking, zooming, and dragging through D3’s `d3.behavior.zoom` and `d3.layout.tree` APIs. Node labels appear inside foreignObject elements, while tooltips and links are also implemented as SVG groups, with transitions animating node positions on updates.

ICE 8 Family Tree Simple

This interactive family tree visualization displays hierarchical relationships using a node-link diagram with expandable and collapsible branches. The D3.js v3 layout algorithm arranges nodes vertically by depth, with color-coded node types and labeled links showing connection directions. Users can click nodes to toggle child visibility, with smooth 750ms animated transitions. The visualization supports pan and zoom through D3's zoom behavior, while tooltips provide additional node information. The tree structure comes from a JSON data file loaded via d3.json, with SVG rendering for all graphical elements including custom arrow markers and drop shadows.

ICE8_Family Tree

A family tree visualization displays hierarchical relationships among named individuals, rendered as an interactive SVG diagram with animated expansion and collapse of branches. Built with D3.js v3 and jQuery, the code uses the `d3.layout.tree` algorithm to compute node positions from the JSON data, then draws rectangular nodes connected by labeled links with directional arrows. Node colors correspond to a `type` field (e.g., type1, type3), and the visualization supports zooming, dragging, and tooltips via D3 behaviors and custom CSS styling, with all tree data defined in the `data-example.json` structure.

ICE8 - Family Tree

A family tree visualization uses hierarchical node-link layout to display three generations of relatives, with each person rendered as a colored rectangle and connections shown as curved links with directional arrows. The D3 v3 tree layout arranges nodes vertically by depth, while a breadth-first traversal dynamically sizes the SVG canvas based on tree width and depth. Implemented in React with vanilla D3 selections, the visualization supports zoom and drag interactions via `d3.behavior.zoom`, and includes tooltips and collision detection for overlapping nodes. Data comes from a nested JSON file, with node colors assigned by generation type.

ICE - 8 : Family Tree

An interactive family tree visualization renders hierarchical data from a JSON file, with nodes colored by generation and connected by links. The D3.js v3 layout algorithm positions the tree, while SVG rectangles and foreignObject elements display node names and text. Users can click nodes to expand or collapse branches, with animations and zooming supported. The visualization adapts its canvas size dynamically based on the tree's depth and width.

ICE8- Family Tree

This visualization presents a family tree as an interactive, animated diagram built with D3.js v3 and React. It shows hierarchical relationships between family members, using colored rectangles for different node types and connecting links with directional arrows. The tree layout is computed with `d3.layout.tree`, and nodes and links are rendered as SVG elements. The visualization supports zooming and dragging via `d3.behavior.zoom`, plus click interactions to expand and collapse nodes. Data is loaded from a JSON file and styled with custom CSS, with tooltips for additional information.

ICE8 - Family Tree

This example renders a family tree as an interactive SVG diagram using D3.js v3. The visualization shows hierarchical relationships between family members, with each node represented by a colored circle and name label. Node size and color encode the member’s value and level, while link strokes inherit the parent’s level color. The code implements a D3 tree layout (`d3.tree()`), uses `d3.hierarchy` to structure the JSON data, and creates curved paths for parent-child links. Circle radius is set by the `value` property, and fill and stroke styles come from the `level` and `type` fields.
