This visualization shows the hierarchical structure of world countries, organized by continent and subregion, as a node-link tree diagram. Built with D3 v5, it uses the `d3.tree` layout and `d3.hierarchy` to process the JSON data, while `d3.linkHorizontal` generates the curved connection paths. Text labels display each country with font sizes scaled by node depth, and the interaction model adds panning and zooming via `d3.zoom`. The SVG rendering employs the margin convention and a custom font, with subtle text shadows for readability.

World Countries Tree

This visualization shows the hierarchical structure of world countries organized by continent and subregion using a tree layout. It displays all countries as text labels connected by curved links, with font size decreasing at deeper levels to indicate hierarchy. The implementation uses D3 v5 with `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal` to compute and draw the layout in SVG. Pan and zoom are enabled via `d3.zoom`, and the data comes from a local `data.json` file containing nested geographic groupings.

World Countries Tree

This visualization shows a hierarchical tree of world countries organized by continent and subregion, using a left-to-right layout with curved links. It renders country and region names as text nodes, with font size decreasing by depth. Built with D3 v5, it uses `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal` to compute the layout and paths, while `d3.zoom` enables panning and zooming. The data comes from a JSON file, and the SVG output is styled with a custom serif font and teal link strokes.

World Countries Tree

This visualization displays the hierarchical structure of world countries, organized by continent and subregion. The tree layout renders countries as leaf nodes beneath their regional groupings, with curved horizontal links connecting parent and child nodes. The visualization uses D3 v5's `tree()` layout and `linkHorizontal()` generator, with text labels sized inversely to node depth. The SVG output is rendered dynamically from a JSON dataset, and users can navigate the hierarchy using D3's `zoom()` behavior for panning and scaling.

World Countries Tree

This interactive visualization displays the hierarchical structure of world countries, organized by continent and subregion. The tree layout uses horizontal links to connect parent nodes to their children, with text labels sized inversely to depth for readability. Built with D3 v5, the code employs `d3.tree` and `d3.hierarchy` to process the nested JSON data, while `d3.linkHorizontal` generates the curved paths and `d3.zoom` enables panning and scaling, rendering everything as SVG elements.

World Countries Tree

This visualization shows the hierarchical structure of world countries organized by continent and subregion, with each country labeled as a leaf node in a tidy tree layout. The tree radiates horizontally from a root node, with font sizes decreasing at deeper levels and country names displayed after their parent regions. Using D3 v5, the implementation applies `d3.tree()` and `d3.hierarchy()` to compute node positions, `d3.linkHorizontal()` to generate curved link paths, and SVG rendering with pan-and-zoom support via `d3.zoom()`. The data comes from a pre-structured JSON file, and text elements include a glow effect via CSS `text-shadow` for readability.
