This radial tree visualization displays Nigeria's hierarchical structure, from geopolitical zones down to individual local government areas. Users can pan and zoom the layout, which positions leaf labels around the circle and centers deeper node labels for legibility. The implementation loads a static JSON file and uses D3 v4’s tree layout (`d3.tree`), custom projection functions, and zoom behavior (`d3.zoom`). Node depth drives font sizing via a square-root scale, while link paths and text positioning rely on the cluster layout’s angular coordinates.

Nigeria Local Government Areas hierarchy

This radial tree visualization displays the hierarchy of Nigeria’s administrative divisions, from geographic zones down to local government areas. Built with D3 v4, it uses the `d3.cluster` layout to arrange nodes in a circular pattern, with SVG paths drawn as curved links between parent and child nodes. The visualization supports panning and zooming through `d3.zoom`. Text labels scale in size based on depth, and leaf nodes are rotated outward for readability. Data is loaded from a local `data.json` file containing the nested structure of regions, states, and LGAs.

RADIAL TREE

This visualization shows the hierarchical structure of world countries organized by continent and subregion, displayed in a radial tree layout. The data comes from a JSON file containing country names grouped into regional categories. Built with D3 v4, the code uses `d3.cluster` and `d3.hierarchy` to compute the radial positions, while `d3.zoom` enables panning and zooming. Labels are rotated and positioned based on depth, with larger fonts for higher-level nodes, and rendered as SVG text with a glow effect.

Fork of Radial Tree of Countries Hierarchy

This radial tree visualizes the hierarchical relationships between world regions and their constituent countries. The data is loaded from a local JSON file and rendered as an SVG, with the root node placed at the center and branches extending outward. The visualization supports panning and zooming interactions through `d3.zoom`, allowing users to explore the hierarchy at different scales. Node labels are rotated and positioned based on their depth and angle, with font size scaling according to hierarchy level. The implementation builds on the `d3.cluster`, `d3.hierarchy`, and `d3.scaleSqrt` APIs.

Fork of Radial Tree of Countries Hierarchy

This radial tree visualization displays a hierarchical breakdown of world countries by continent and subregion, with each node labeled by name and scaled by depth. The layout uses a D3 cluster layout, projecting nodes in a circular arrangement from a central root. Users can pan and zoom the SVG canvas via d3.zoom. The data, loaded from a JSON file, is structured hierarchically, and the code adapts Curran Kelleher’s original block by adjusting link paths and text rotation for readability.

Radial Tree of Countries Hierarchy Example

A radial tree visualization displays the hierarchy of world countries organized by continent and subregion. Built with D3 v4, it uses the `d3.cluster` layout and custom projection functions to position nodes in a circular arrangement. The visualization supports panning and zooming via `d3.zoom`, with interactive transforms applied to the SVG group. Node labels vary in font size based on depth, and curved paths connect parent-child relationships. The data comes from a local JSON file structured around geographic regions.

RADIAL TREE

A radial tree displays a hierarchy of world countries, organized by continent and subregion, radiating outward from a central root node. The visualization uses an SVG rendering with D3 v4’s `d3.cluster` layout to position nodes, and custom bezier paths for links. Text labels are rotated and sized by depth, with a heavy white glow for readability. Panning and zooming are implemented via `d3.zoom`, while the JSON data structure defines the nested country groupings.

Fork of Radial Tree of Countries Hierarchy

This radial tree visualization displays a hierarchical structure of world countries, categorized by continent and subregion, with the depth of each node conveyed through font size. The tree is rendered as an SVG using d3.cluster, with curved links connecting parent and child nodes and text labels positioned radially around the center. The visualization supports panning and zooming via d3.zoom, which applies a transform to the entire tree group. Data comes from a local JSON file, and the text often includes a white glow effect for readability against the background.

Fork of Radial Tree of Countries Hierarchy

This radial tree visualization displays the hierarchical structure of world countries, organized by continent and subregion. It uses a circular layout where leaf nodes representing individual countries are positioned at the outer ring, with intermediate labels for continents and regions shown with larger fonts. The visualization supports interactive panning and zooming through the `d3.zoom` API, which updates an SVG group’s transform based on user gestures. The tree layout is computed using `d3.hierarchy` and `d3.cluster`, with links drawn via cubic Bézier curves and text labels rotated to follow the radial orientation. Data comes from a local JSON file (`data.json`) containing the full country hierarchy.
