This radial tree visualization displays a hierarchical organization of countries grouped by continents and subregions, with each country name positioned along circular branches radiating from a central "World" node. The code uses d3.hierarchy and d3.cluster to compute the tree layout, then projects node positions into polar coordinates for the radial arrangement. SVG paths with bezier curves connect parent and child nodes, while text labels employ font sizing based on depth and rotation for smaller branches. Panning and zooming are enabled through d3.zoom, applied to an SVG group containing all links and labels.

Fork of Radial Tree of Countries Hierarchy

This radial tree visualization shows the hierarchical structure of world countries, organized by continent and subregion, with each country as a leaf node. The circle-packing layout positions nodes radially, and the code uses `d3.hierarchy` and `d3.cluster` to compute the layout, with `d3.zoom` enabling pan and zoom interactions on the SVG. Link paths are generated manually via a projection function, and text labels adjust rotation and anchor based on depth and angle, with font size scaled by depth.

Fork of Radial Tree of Countries Hierarchy

A radial tree shows the hierarchical organization of countries by continent and subregion, branching outward from a central "World" root. D3’s cluster layout computes angular and radial positions, while SVG paths connect parent-child nodes. Panning and zooming are enabled via d3.zoom. Node labels use hue-free teal links and font sizes scaled by depth, with text rotation applied for deep leaves. Data comes from a JSON hierarchy.

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 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.

Fork of Radial Tree of Countries Hierarchy

This radial tree visualizes the hierarchical relationships between world countries, grouped by continent and subregion. Using D3.js v4, it renders a circular cluster layout where nodes are positioned by angle and radius. The visualization reads a nested JSON file and uses `d3.cluster` to compute positions, `d3.hierarchy` to process the tree structure, and `d3.zoom` to enable panning and zooming interactions. The code uses `project()` for polar-to-Cartesian conversion and styles text with different font sizes and rotations based on depth.

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.

Fork of Radial Tree of Countries Hierarchy

This radial tree visualization displays the hierarchical structure of world countries organized by continent and subregion. The visualization uses a circular layout with connecting bezier curves, where text labels are rotated and positioned according to their depth in the hierarchy. The code implements interactive panning and zooming through `d3.zoom`, while the tree layout is computed using `d3.cluster`. Text sizing scales with depth using `d3.scaleSqrt`, and the SVG rendering includes a glow effect on labels for improved readability.

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.
