This animated family tree visualizes the hierarchical relationships between animal species, using colored nodes to distinguish generations. The data is organized with `d3.stratify()` and laid out with `d3.tree()`, producing SVG paths that animate into position over 1.5 seconds. Node squares use a custom element with a `transition()` to grow to their final radius, while text labels display species names. All elements are rendered in SVG using D3 v6, with generation-specific fill colors and green animated connecting links.

Family Tree

A family tree visualization displays hierarchical parent-child relationships across four generations, with nodes colored by depth and labeled with character names. Each connection animates from a horizontal line into a diagonal link as the tree expands. The implementation uses D3 v6’s `d3.stratify()` to build the hierarchy from flat data and `d3.tree()` to compute layout positions, while SVG circles, text, and paths are rendered with transitions on `attr` for smooth node growth and link drawing.

Family Tree (

This example shows an animated family tree built with D3.js v6. It visualizes hierarchical relationships between family members using a tree layout, with nodes as circles colored by generation depth and connected by lime-green links. The data is defined as an array of child-parent pairs, processed with `d3.stratify()` and `d3.tree()`. The SVG rendering animates path connections and circle radii using `transition().duration()`, and labels each node with the child name.

Family Tree

This family tree visualization displays a hierarchical dataset of family members across several generations, with nodes colored by generation and connected by animated green links. Built with D3.js v6, the code uses the `d3.stratify()` utility to structure the parent-child data and `d3.tree()` to compute the layout. Nodes are rendered as SVG circles with a 1.5-second path-drawing transition, while text labels identify each person. Generation colors are assigned via a custom `setGenerations()` switch function, ranging from orange for the root to teal for deeper levels.

Family Tree

This example presents a three-generation family tree as a static, animated diagram. Circular nodes, colored by generation (blue, red, brown), represent individuals, while black connecting lines show parent-child relationships. The visualization uses d3.stratify() to convert the flat parent-child data into a hierarchy and d3.tree() to compute node positions. Nodes and links animate into place via the `.transition().duration()` API, with all elements rendered as SVG.

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

A family tree displays ten nodes connected by animated paths, with each circular node labeled by a family member's name. The visualization uses D3 v6's `d3.stratify()` to build a hierarchy from flat parent-child data, followed by `d3.tree()` to compute node positions. SVG circles and text elements are rendered on a black background, with lime-green strokes and light-green fills. Paths between nodes animate from zero length to full connections over one second, while circles expand over 800 milliseconds, creating a sequential reveal of the hierarchical relationships.

Family Tree

This example visualizes a family tree as a branching set of animated nodes and links on a black background. The SVG renders green circles for each person and straight lime-colored paths that connect parents to children, with names labeled inside the nodes. The code builds the hierarchy from an array of child-parent pairs using `d3.stratify` and `d3.tree`, then animates the paths and circles with `transition()` and `duration()`. Both the connections and nodes are appended to a single `<g>` element, and text labels are positioned using the tree’s computed x and y coordinates.

Family Tree

This example shows a family tree with animated connections and labeled circular nodes on a green background. The tree is built from hardcoded parent-child data using `d3.stratify()` and laid out with `d3.tree()`. SVG elements render the visualization, with paths animating from source to target positions via `transition().duration(1000)`, while circles and text labels appear with a shorter transition. The code uses D3 v6 and appends all elements directly to the body.
