A static tree visualization displays the hierarchical structure of world regions and countries, from continents down to individual nations. The layout uses `d3.tree()` to compute node positions and `d3.linkHorizontal()` to draw the connecting paths between parent and child nodes, rendered as SVG paths. Country and region names appear as text labels sized according to their depth in the hierarchy. The data comes from a local JSON file, and the visualization includes zoom functionality via `d3.zoom` for exploring the full tree structure.

This radial tree visualization displays the hierarchical relationships between world regions, subregions, and countries, with text labels sized by depth. The d3.cluster layout positions nodes radially, and d3.svg paths connect parent-child nodes with curved links. Users can pan and zoom the entire visualization using d3.zoom, which applies a transform to a container group. The code reads country data from a JSON file using d3.json, and the font sizes scale with depth via d3.scaleSqrt, creating a clear visual hierarchy.

Building a Tree Visualization

This visualization displays a hierarchical tree of world regions and countries, branching from a central root through continents and subregions to individual nations. The layout uses a left-to-right tree structure with horizontal connector lines, rendered as SVG paths. The code builds the hierarchy with `d3.hierarchy`, computes positions with `d3.tree`, and draws curved links using `linkHorizontal`. Text labels are positioned at each node with font sizes decreasing by depth, and a `d3.zoom` handler enables panning and scaling of the entire diagram. The data comes from the embedded `data.json` file.

Data Tree

This visualization shows a hierarchical tree of world regions and countries, with countries nested under their respective continents and subregions. The tree is rendered with SVG paths connecting parent and child nodes, using a horizontal layout where text labels display country names at sizes that decrease with depth. The code uses D3 v5’s `tree`, `hierarchy`, and `linkHorizontal` APIs to compute the layout, and includes zoom functionality via `d3.zoom`. Data comes from a static JSON file containing the geographic hierarchy.

This is a radial tree visualization of a hierarchical dataset of world countries, organized by continent and subregion. The visualization uses d3.cluster to compute the radial layout and d3.zoom with SVG transforms for panning and zooming. Text labels are rotated and positioned based on depth within the hierarchy, with leaf nodes placed along the outer edge. The data is loaded from a local JSON file using d3.json.

World Countries Tree

This D3.js visualization shows the hierarchical structure of world countries, organized by continent and subregion, using an indented tree layout. The SVG rendering displays country names as text nodes connected by curved paths, with font size decreasing at each depth level to emphasize the hierarchy. The code uses `d3.json` to load the country data, `d3.tree` for layout, `d3.hierarchy` for nesting, and `d3.linkHorizontal` for the link paths. A custom `d3.zoom` event handler enables interactive pan and zoom of the entire visualization.

Country Tree

This visualization displays the hierarchical structure of world countries organized by continent and subregion, rendered as a horizontal tree layout using D3.js. The tree branches show the geographic grouping from World through Asia down to individual nations. The visualization uses D3's `tree`, `hierarchy`, and `linkHorizontal` functions to compute and draw the layout with SVG paths and text elements. Interactive zooming is enabled via D3's `zoom` event, and node labels are sized proportionally to their depth in the hierarchy.

World Countries Tree

This interactive visualization displays the hierarchical structure of world countries organized by continent and subregion, rendered as an indented tree layout. It uses D3.js v5 with the `tree`, `hierarchy`, and `linkHorizontal` APIs to compute positions and draw links, along with `zoom` and `event` for pan-and-zoom interaction. The data is loaded from `data.json` via `json()`. Node labels show country names with font size decreasing by depth, and the SVG output uses a teal stroke for connecting paths.

World Countries Tree

This visualization displays a tree diagram of world countries nested by continent and region, with each leaf node labeled by country name. It uses the D3 v5 library, specifically `d3.tree` and `d3.hierarchy`, to compute the layout, and `d3.linkHorizontal` to generate the curved link paths. The SVG rendering is styled with teal strokes and serif font text, and includes zoom interaction via `d3.zoom`. Font size scales inversely with tree depth, making top-level regions larger. The example is built around two data files (`data_v1.json` and `data_v2.json`) that structure the hierarchical world geography.
