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.

The visualization shows a radial tree of country hierarchies, with continents branching into subregions and individual countries around the center. User interaction includes panning and zooming across the SVG canvas. The code uses D3 v4’s `d3.cluster`, `d3.hierarchy`, and `d3.zoom` APIs to layout the hierarchical data, draw curved link paths, and apply text rotation based on angular position. Data comes from a JSON file containing nested continent-region-country entries.

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.

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.

Fork of Radial Tree of Countries Hierarchy

This radial tree visualizes the hierarchical structure of world countries, organized by continent and subregion, using data from `data.json`. Built with D3 v4, it renders an SVG and supports panning and zooming via the `d3.zoom` interaction. The tree layout is computed using `d3.hierarchy` and `d3.cluster`, with links drawn as curved paths. Text labels use font sizes scaled by depth, and the layout is adapted from Curran Kelleher’s World Countries Hierarchy block.

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 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.

A radial tree diagram visualizes the hierarchy of world countries, grouped first by continent and then by subregion. The visualization uses a D3 v4 cluster layout, with SVG paths depicting connecting links and text labels for each country. The code employs `d3.hierarchy`, `d3.cluster`, and `d3.zoom` to enable panning and zooming of the entire diagram. Data is loaded from a local `data.json` file and rendered with a linear gradient of font sizes based on depth in the hierarchy.
