This visualization presents a hierarchical tree of world countries, organized by continent and subregion, using a left-to-right node-link diagram. The d3.js library builds the tree layout, positions nodes with `tree()` and `hierarchy()`, and draws curved link paths via `linkHorizontal()`. Node labels are placed at varying font sizes based on their depth. The data is loaded from a local `data.json` file and rendered as an SVG, with zoom functionality enabled through a d3 zoom event handler.

World Countries Tree

This visualization shows the hierarchical structure of world countries organized by continent and subregion. It renders a horizontal tree layout using D3’s `tree()` and `hierarchy()` functions, with countries positioned as leaf nodes. Links are drawn as curved paths via `linkHorizontal()`, while node labels use varying font sizes based on depth. The entire visualization is placed inside a zoomable group, allowing users to pan and scale through the `d3.zoom()` API. Data comes from a local `data.json` file, and the SVG output is styled with custom CSS, including a serif font and green link strokes.

World Countries Tree

This visualization displays the hierarchical structure of world countries, organized by continent and subregion, as a horizontal tree diagram rendered as SVG. It uses a D3.js v5 tree layout to position nodes and links, with the `d3.hierarchy` and `d3.linkHorizontal` modules generating the tree paths. The data is loaded from `data.json`, and the visualization supports mouse-wheel zooming via d3's zoom transform, applying it to a group element. Text labels show country names with a font size that decreases with tree depth.

World Countries Tree

This visualization displays a hierarchical tree of world countries organized by continent and subregion, using a left-to-right layout with curved links and text labels sized by depth. The data is loaded from a JSON file and processed with `d3.hierarchy` and `d3.tree`, while `d3.linkHorizontal` generates the paths and `d3.zoom` enables panning and zooming on the SVG. Text styling relies on CSS `text-shadow` for readability, and the layout adapts to the full browser viewport.

World Countries Tree

This visualization displays the hierarchical structure of world countries organized by continent and subregion, using a horizontal tree layout rendered as SVG. The code employs D3 v5's `tree()` and `hierarchy()` functions to compute node positions and draws curved links with `linkHorizontal()`. Static labels are placed at each node, and the data comes from a local `data.json` file containing the nested geographic classification.

World Countries Tree

This visualization shows the hierarchical structure of world countries, organized by continent and subregion, as a horizontal tree layout. The data is loaded from a JSON file and rendered as SVG. Using d3.tree, d3.hierarchy, and d3.linkHorizontal, the code draws curved links between nodes and displays country names with font sizes that decrease by depth. The visualization supports zooming and panning via d3.zoom, with a Playfair Display font and teal-colored paths for the connections.

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 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.
