This visualization displays a hierarchical tree of world countries, grouping them by continent and subregion. The data, sourced from a JSON file, is organized from a root "World" node down through regional categories. D3.js v5 is used to render the structure as horizontal links and text labels on an SVG canvas. The implementation employs D3's `tree` layout, `hierarchy`, `linkHorizontal`, and `zoom` APIs to create the expandable tree. The display features a custom Playfair Display font and applies a font-size based on the node's depth in the hierarchy.

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.

World Countries Tree

This visualization presents the hierarchical structure of world countries, organized by continent and subregion, as a horizontal tree diagram. The layout uses a `d3.tree` layout with `d3.hierarchy` and renders nodes as labels and edges as horizontal links via `d3.linkHorizontal`. Node text size decreases with depth, and the view supports zooming through a `d3.zoom` event handler. Data is loaded from a JSON file, styled with the Playfair Display font, and rendered as an SVG with a green stroke for connections.

World Countries Tree

This D3.js visualization uses a hierarchical tree layout to display the geographic structure of world countries, organized by continent and subregion. The data is loaded from a JSON file and processed through D3’s hierarchy function, with links drawn as horizontal connectors and text labels positioned per node depth, using the Playfair Display font. The visualization supports zooming via D3’s zoom component, allowing interactive exploration of the tree. The SVG rendering applies a fixed color to the connection paths, while node text includes a white shadow for readability.

World Countries Tree

This visualization shows a hierarchical tree of world countries, organized by continent and subregion, with the country names displayed as text labels. The tree layout uses `d3.tree` and `d3.hierarchy` to position nodes, while `d3.linkHorizontal` generates curved paths for the connections. The SVG rendering includes zoom functionality via `d3.zoom`, allowing interactive pan and scale. Data is loaded from a JSON file containing geographical groupings, and text styling uses the Playfair Display font with font sizes that decrease with node depth.

World Countries Tree

This visualization displays the hierarchical structure of world countries, organized by continent and subregion, as a horizontal tree diagram. The data is sourced from a JSON file representing countries by geographic region. Using d3.js v5, the layout is computed with `d3.tree` and `d3.hierarchy`, with links drawn via `d3.linkHorizontal`. Each country name appears as text, with font size scaling by depth. The SVG rendering supports zoom and pan through a `d3.zoom` interaction, allowing exploration of the full tree. Text styling uses the Playfair Display font, with white shadows for legibility.

World Countries Tree

This visualization displays a hierarchical tree of world countries, organized by continent and subregion. It shows the structural relationships between geographical groupings, with each node labeled by name. The chart uses D3.js v5's `tree` layout and `hierarchy` functions to compute the graph, and `linkHorizontal` paths to draw the connecting lines. Data is loaded from a JSON file, and the visualization supports interactive zooming via a custom `zoom` event, with labels styled using the Playfair Display font.

World Countries Tree

This visualization presents the hierarchical structure of world countries, organized by continent and subregion, as a horizontal tree diagram. Each node displays a country or region name, with font size decreasing at deeper levels. The tree layout uses D3’s `tree` and `hierarchy` functions, with `linkHorizontal` drawing the curved connections. Pan and zoom are enabled via `d3.zoom`, while text labels include white shadows for readability. Data comes from a JSON file with nested children, rendered as SVG elements with a custom Playfair Display font.
