This visualization displays a hierarchical tree of world countries, organized by continent and subregion, with the root node labeled "World" branching down to individual nations. It shows the structural relationships between geographic regions and their constituent countries. The tree is rendered as an SVG using D3.js v5, with the `d3.tree` layout algorithm and `d3.linkHorizontal` for curved edges. Text labels scale in font size based on node depth, and the visualization supports zooming via a custom zoom event. Data is loaded from a JSON file structured as nested regions.

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 the hierarchical structure of world countries, organizing them by continent and subregion into a horizontal tree layout. The root node, "World," branches into continents like Asia, which further divide into subregions and individual countries. The SVG rendering uses D3.js v5’s `d3.tree`, `d3.hierarchy`, `d3.linkHorizontal`, and a zoom interaction via `d3.zoom` to navigate the large dataset. Node labels are positioned with dynamic font sizes based on depth, and the data loads asynchronously from a JSON file.

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 with D3.js. The interactive visualization supports pan and zoom navigation through D3’s zoom behavior. Node labels are scaled by depth level, with links drawn using d3.linkHorizontal. The data is loaded from a JSON file containing nested country groupings under a World root node.

World Countries Tree

This visualization displays a hierarchical tree of world countries, organized by continent and subregion, with each country as a leaf node. The tree layout uses d3.tree and d3.hierarchy to position nodes and links, while d3.linkHorizontal draws the connecting paths. Text labels show country and region names, with font size decreasing by depth. The SVG rendering supports pan and zoom via d3.zoom, and the data comes from the included data.json file.

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 visualization displays the hierarchical structure of world countries, organized by continent and subregion, using a horizontal tree layout rendered as SVG. The code uses D3 v5's `tree` layout and `linkHorizontal` path generator to position nodes and draw connecting links, with country names displayed as text labels sized by depth. Data comes from a JSON file containing a nested structure of world regions and countries, while zooming is implemented via D3's `zoom` behavior.
