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 presents the hierarchical structure of world countries organized by continent and subregion, displayed as a horizontal tree layout. The hierarchical data is loaded from a JSON file and rendered as an SVG using D3 v5’s `tree` layout, `hierarchy`, and `linkHorizontal` path generator. Node labels are positioned according to their depth, with font size decreasing at deeper levels, and the entire graphic supports pan and zoom via D3’s `zoom` behavior.

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 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.

World Countries Tree

This visualization displays a hierarchical tree of world countries organized by continent and subregion, using data from a nested JSON file. Each country is shown as a text label, positioned according to its depth in the hierarchy, with connecting paths. The D3 v5 library powers the layout, using `d3.tree()`, `d3.hierarchy()`, and `d3.linkHorizontal()` to compute positions and draw the SVG paths. Text labels are rendered with varying font sizes based on depth, and the entire tree can be zoomed and panned via `d3.zoom()`.

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 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. The layout uses a tree diagram with horizontal links connecting parent nodes to their children, and text labels sized inversely to depth. The implementation leverages d3.hierarchy, d3.tree, and d3.linkHorizontal to compute positions and draw SVG paths, while d3.zoom enables panning and scaling of the entire tree. Data comes from a JSON file containing the geographic classification of nations.
