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

A family tree displays three generations of relatives as orange circles connected by green lines on a pink background. Using D3 v6, the code builds a hierarchical layout with `d3.stratify()` and `d3.tree()`, then renders SVG paths and circles with animated transitions. Node labels show each person's name, while the tree expands from a single root ancestor through children and grandchildren.

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

A family tree visualization renders hierarchical relationships as an SVG diagram. Colored circles mark each person, with blue, yellow, and orange indicating their depth in the tree, while curved paths connect parents to children. The example uses D3 v5, but notably relies on the missing `d3.stratify` and `d3.tree` APIs, which are not part of the standard D3 library. The code manually positions nodes and links using the x and y coordinates from those undefined functions, with hard-coded data listing individuals and their parents.

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 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.

Familytree

A family tree diagram visualizes hierarchical relationships among named nodes, with generations distinguished by color (yellow, pink, skyblue, orange). The example uses D3 v6’s `d3.stratify()` to build the hierarchy from flat parent-child data, then `d3.tree()` to compute node positions. SVG circles and text labels render each entry, while paths between nodes animate in with `transition()`, drawing lime-colored connections over one second.

Family Tree

This visualization displays a family tree using D3.js, with each node representing a family member and colored by generation level. The root, "cherry," branches to two children, which then expand into three generations of descendants. The code uses `d3.stratify()` to build the tree structure from the flat data and `d3.tree()` to calculate the node positions. SVG paths are animated to draw connections between nodes, while circles represent members with labels, all rendered on a grey background using SVG elements.
