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.

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 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 displays the hierarchical structure of world countries organized by continent and region, rendered as a horizontal tree layout. The D3.js code uses `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal` to compute node positions and draw curved links from the hierarchical JSON data. Each country name appears as SVG text with font size decreasing by depth, while pan and zoom are enabled through `d3.zoom` on the entire SVG group.

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 shows the hierarchical structure of world countries organized by continent and subregion using a horizontal tree layout. The code renders an SVG with d3.tree and d3.hierarchy to position nodes, while d3.linkHorizontal generates the curved connecting paths. Interactive zooming is enabled through d3.zoom, and text labels display country names with font sizes decreasing by depth level. The data comes from a nested JSON file containing geographic groupings, and nodes are labeled with d3 selections appending text elements styled with Playfair Display font.

World Countries Tree

This visualization shows a hierarchical tree of world countries, organized by continent and sub-region. The tree layout displays each country as a text label, with branching paths connecting nations to their regional groupings, using a zoomable interface for navigation. The code uses d3.hierarchy and d3.tree to compute the layout, d3.linkHorizontal for the connecting paths, and d3.zoom for panning and scaling. Data comes from a nested JSON file, and the SVG rendering highlights the structure with teal links and Playfair Display typography.
