This visualization presents a radial tree of countries organized by continent and subregion, with the hierarchy derived from JSON data. The layout uses `d3.cluster` to position nodes in a circular arrangement, with curved links drawn as SVG paths. Text labels display each country or region name, with font sizes scaled by depth using `d3.scaleSqrt`. Panning and zooming are implemented through `d3.zoom`, which applies transformations to the SVG group containing all elements. The design adapts Curran Kelleher’s original block, rendering all content as SVG elements within a fixed viewport.

Radial Tree of Countries Hierarchy

This radial tree visualization displays the hierarchical structure of world countries, organized by continent and subregion. Built with d3.v4, it uses the d3.cluster layout to position nodes in a circular arrangement, with SVG paths connecting parent and child nodes. The visualization supports panning and zooming interactions through d3.zoom, and text labels are rotated and sized based on their depth within the hierarchy, with the data sourced from a nested JSON file.

Radial Tree of Countries Hierarchy

This radial tree visualization displays the hierarchical structure of world countries, organized by continent and subregion, with leaf nodes representing individual nations. The D3 v4 `d3.cluster` layout positions nodes in a circular arrangement, while SVG paths connect parent and child nodes. Nodes are labeled with country names whose font size scales with depth using a `d3.scaleSqrt`. Panning and zooming are enabled through `d3.zoom`, and the data comes from the embedded `data.json` file.

Radial Tree of Countries Hierarchy

This radial tree visualization displays a hierarchical organization of countries grouped by continent and subregion, with each leaf node labeled and connected by curved paths from a central root. The D3 v4 code uses `d3.cluster` to compute the tree layout, `d3.hierarchy` to parse the JSON data, and SVG paths for the links. Text nodes vary in size based on depth, and a zoom behavior with panning is enabled via `d3.zoom`. The data comes from a local `data.json` file containing the country hierarchy.

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.

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

This radial tree visualization displays the hierarchical relationship of world countries, organized by continent and subregion, with the root node "World" at the center. The layout uses D3's `d3.cluster` to position nodes radially, and SVG paths connect parent and child nodes with curved links. Text labels show country and region names, with font sizes scaled according to depth using `d3.scaleSqrt`. Users can pan and zoom the entire visualization via `d3.zoom`, which applies an SVG transform to the containing group. Data is loaded from a local JSON file.

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.

Fork of Radial Tree of Countries Hierarchy

This radial tree visualization displays a hierarchical breakdown of world countries organized by continent and subregion, with each node labeled at its corresponding depth level. The visualization supports panning and zooming through the `d3.zoom` API, which applies transforms to the SVG group element. The code uses `d3.cluster()` to compute node positions in a circular layout and `d3.scaleSqrt` to size the text based on tree depth. Links draw as curved paths for deeper nodes, while leaf nodes align text to the outer edge for readability. The data originates from a JSON file containing the full country hierarchy.
