This interactive visualization presents the hierarchical structure of world countries, organized by continent and subregion. It uses a horizontal tree layout, with the root node on the left and leaf nodes (countries) extending to the right. The D3.js library (v5) computes the tree layout via `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal`. Pan and zoom are handled through `d3.zoom`. The data is loaded from `data.json` and rendered as SVG paths and text elements, with node labels sized by depth.

World Countries Tree

This interactive tree diagram visualizes the hierarchical structure of world countries, organized by continent and subregion. Using D3.js v5, the visualization employs a horizontal tree layout with SVG rendering. The code leverages D3's `tree`, `hierarchy`, and `linkHorizontal` APIs to compute the layout and generate connecting paths. User interaction is supported through D3's `zoom` event, which applies pan and zoom transformations to the entire group. Text labels display country names, with font size decreasing by depth level, while the data source is a JSON file containing the geographical hierarchy.

World Countries Tree

This visualization shows the hierarchical organization of world countries, grouped first by continent and then by subregion, with each country displayed as a leaf node. The tree layout positions nodes horizontally, and text size decreases with depth to emphasize the structure. Built with D3 v5, it uses `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal` to compute and draw the connections as SVG paths. Pan and zoom interactions are enabled via `d3.zoom`, and the data is loaded from a local JSON file structured with nested children arrays.

World Countries Tree

This visualization displays the hierarchical structure of world countries, organized by continent and subregion, as a horizontal tree diagram. The root node represents the data source, with branches expanding outward to reveal geographic groupings and individual countries. The code uses D3.js v5, implementing a tree layout with `d3.tree()` and `d3.hierarchy()` to process hierarchical JSON data. Nodes are rendered as SVG text elements connected by horizontal links generated with `d3.linkHorizontal()`, and the entire visualization supports pan and zoom through D3’s zoom behavior.

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 interactive visualization displays the hierarchical structure of world countries, organized by continent and subregion, using a horizontal tree layout. It loads country data from a JSON file and renders it as an SVG with D3’s `tree` and `hierarchy` functions, connecting nodes with `linkHorizontal` paths. Text labels scale in font size by depth, and the entire view can be panned and zoomed via D3’s `zoom` handler applied to a group element.

World Countries Tree

This visualization displays the hierarchical structure of world countries, organized by continent and subregion, as an interactive tree diagram. The D3.js visualization (v5) uses the `tree` layout algorithm with `linkHorizontal` edges to render the hierarchy as an SVG, with node labels sized inversely to their depth in the tree. The code loads country data from a JSON file, applies a `hierarchy` transformation, and supports zooming and panning via the `zoom` event, which adjusts the transform of the SVG group containing the tree.

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.
