This example shows a family tree visualization with color-coded nodes for each person, arranged hierarchically from a single root ancestor down through multiple generations. The tree renders as an SVG, with horizontal links connecting parent and child nodes, and labels sized according to depth in the hierarchy. The code uses d3.hierarchy and d3.tree to compute the layout, and d3.linkHorizontal for the curved connecting paths. A d3.zoom handler enables panning and zooming the entire visualization. Node colors and text are drawn from the JSON data, with a custom Playfair Display font applied via CSS.

Fork of Different Family Tree

This visualization presents a family tree as a horizontal dendrogram, with nodes connected by orange links and labeled with names from a JSON dataset. Node color encodes different branches of the lineage, while font size decreases with each generation to show depth. The example uses D3 v5’s `tree`, `hierarchy`, and `linkHorizontal` components to compute the layout, with SVG rendering and zoom functionality enabled via D3’s `zoom` and `event` APIs. The visualization is built within a React framework, and text elements are styled with a Playfair Display font.

Fork of Family Tree

This interactive family tree visualization displays hierarchical relationships between named individuals, with color-coded nodes indicating different family types. The tree renders as an SVG using D3 v3's tree layout and includes pan-and-zoom functionality through d3.behavior.zoom. Nodes are clickable and expand or collapse their children with animated transitions. The data comes from a JSON file, and the implementation uses jQuery alongside D3 for DOM manipulation, styling nodes, links, and tooltips with custom CSS classes.

Fork for the Family Tree

This visualization displays a color-coded family tree as a horizontal dendrogram, with the root "josh" branching into children and grandchildren. The tree layout uses `d3.tree` with horizontal links generated by `d3.linkHorizontal`, rendered as SVG paths that are zoomable via the `d3.zoom` event handler. Node labels are positioned using the layout's computed coordinates and styled with font sizes scaled by depth, while each node's fill color comes from the `color` property in the JSON data. The data is parsed from `data.json` using `json`, and the hierarchical structure is built with `d3.hierarchy`.

Family Tree

This interactive family tree displays hierarchical relationships across multiple generations, with each node labeled by name and colored according to its position in the lineage. The visualization uses D3 v5’s `tree` layout to compute node positions and `linkHorizontal` to draw curved connecting paths, while the `zoom` function enables panning and scaling of the SVG canvas. The included JSON data file provides the family structure, and the code explicitly assigns font sizes based on tree depth and text colors from the data attributes.

Fork of Fork of Family Tree

This interactive family tree visualizes hierarchical relationships using nested nodes and connecting links, with each person represented as a colored rectangle labeled by name and type. The tree expands and collapses on click, and supports pan and zoom via mouse interactions, while tooltips display additional link information. Built with D3.js v3 and React, the SVG-based animation uses the `d3.layout.tree` algorithm to position nodes and `d3.behavior.zoom` for navigation, with data loaded from a JSON file defining the family structure.

Fork of Fork of ICE 8 Family Tree

This example displays a family tree as a horizontal dendrogram, with each node colored according to its branch. The visualization uses D3 v5’s `tree` layout and `hierarchy` to compute node positions, while `linkHorizontal` generates the curved links between parent and child nodes. Interactive pan and zoom are enabled via D3’s `zoom` behavior, and SVG `text` elements render labels with sizes scaled by depth. The data is loaded as JSON and parsed with `d3.json`, with node colors applied directly from the dataset’s `color` property.

familytree

This example renders a zoomable hierarchical tree visualization, displaying a color-themed taxonomy where root categories like Black, Blue, and Green branch into related items. The code uses D3 v5's `tree`, `hierarchy`, and `linkHorizontal` functions to compute the SVG layout, with node labels colored via data attributes and text shadows applied through CSS. Zooming is implemented using the `zoom` event, while font sizes scale based on node depth. The data loads from a local JSON file.

Fork of Famil Tree

This fork of a family tree visualizes hierarchical parent-child relationships using a static dataset of names. The graph displays nodes as light green circles connected by maroon paths, with each node labeled by its corresponding family member's name. The visualization uses d3.stratify to structure the data, d3.tree to compute the layout, and transitions on both the connecting paths and node labels to animate the rendering. SVG elements are created and styled through standard d3 selections, with text labels appearing after a depth-based delay.
