Forked from Tree

This example shows a family tree as a hierarchical node-link diagram, where each person appears as a circular node and relationships are drawn as straight black links. The tree layout is computed with `d3.stratify` and `d3.tree`, positioning generations vertically with distinct fill colors. Nodes and links are rendered as SVG circles and paths, with transitions animating link drawing from the parent outward and text labels fading in per depth. The code uses `transition().duration()` to stagger animations and defines custom colors per generation depth.

ICE-8 Family Tree

A family tree visualization displays multiple generations of relatives, with nodes colored by generation depth and animated links forming parent-child connections. The example uses D3 v6 with the `d3.stratify()` and `d3.tree()` layout APIs to structure hierarchical data, rendering SVG circles and text labels. Node and link transitions animate over 1.5 seconds, while distinct fill colors—from light blue to dark teal—differentiate each generation level. The data is defined inline as an array of parent-child relationships.

ICE 8 example of family Tree

This visualization displays a family tree using a hierarchical layout, with pink circles representing individuals and black lines showing parent-child connections. It begins by flattening the data into an SVG canvas, then uses `d3.stratify()` to transform the flat list into a hierarchy and `d3.tree()` to compute node positions. The animation is achieved through D3 transitions that draw the connecting paths over one second and fade in the circles. Text labels appear sequentially, with a delay based on each node’s depth, revealing the tree’s structure dynamically.

ICE 8 - Family Tree

This D3.js v5 example renders a family tree as a tidy tree layout using SVG. The visualization shows three generations of a family, with nodes colored by depth: violet for the root, steelblue for the second level, and gold for the deepest leaves. The code builds the hierarchy with `d3.stratify()`, computes positions via `d3.tree()`, and draws curved cubic Bézier links between parent and child nodes, with each person's name labeled to the right of their node.

ICE - 8 Tree

A family tree visualization uses D3.js and SVG to show an eight-generation hierarchy of named individuals. The tree is built with `d3.stratify` from flat parent-child data and laid out by `d3.tree`. Animated transitions expand the link paths and circle nodes, while node fill colors encode generation depth via a custom `setGeneration` function. Text labels identify each person.

ICE 8 Family Tree d3.js

This example builds a family tree visualization using D3.js v5 and SVG. It maps a flat list of parent-child name pairs through `d3.stratify()` and `d3.tree()` into a hierarchical layout, drawing curved link paths between generations. Each person appears as a colored circle, with fill color determined by tree depth via a switch on `d.height`, and a text label beside each node. The tree spans 860 by 310 pixels, with light blue, salmon, and green shades distinguishing lineage levels.

ICE 8: My Family Tree

This example displays a family tree as a set of colored, animated circles linked by straight lines. The data is a small list of parent-child relationships. Using D3.js v6, the code applies a `d3.stratify()` layout to build a hierarchy, then renders it with a `d3.tree()` layout. Each generation is assigned a distinct color via a custom function, and circles and connecting paths are drawn to an SVG. A transition smoothly animates the initial state of the branches and nodes.

ICE 8 - Family Tree

This visualization displays a family tree as a tidy tree layout using D3.js v5. The code defines hierarchical data with parent-child relationships and renders it as an SVG, with circular nodes colored by depth (green for the root, red for the second level, and blue for deeper nodes). Curved paths connect parent and child nodes using cubic Bézier commands. Each node is labeled with the person’s name. The example uses D3’s `stratify`, `tree`, and `links` APIs to compute the layout and structure.

11540639-ICE 8 Family Tree

A D3.js family tree visualization renders hierarchical data with animated transitions, showing twelve individuals connected by parent-child links in an SVG layout. The tree uses `d3.stratify` to convert the flat data structure into a hierarchy, then `d3.tree` to compute positions. Circles represent family members, colored by generation depth via a switch-case function, with labels appearing progressively. Connections animate through `transition` methods, drawing crimson paths between nodes over 1300 milliseconds.
