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 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.

World Countries Tree

This visualization displays the hierarchical structure of world countries organized by continent and subregion, using a horizontal tree layout. The data, sourced from a JSON file, positions country names with larger text for higher-level regions and smaller text for individual nations. The visualization employs d3.tree and d3.hierarchy to compute the layout, while d3.linkHorizontal generates the curved connecting paths. The SVG rendering supports zooming and panning through d3.zoom, with a Playfair Display font for labels and mint-green colored links against a white background.

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 employs D3 v5’s `tree`, `hierarchy`, and `linkHorizontal` to compute positions and draw curved links, with each node labeled by its region or country name. Users can pan and zoom via `d3.zoom`, with font sizes scaling by node depth. Data comes from a static `data.json` file, and text styling uses the Playfair Display font with white shadows for legibility.

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 an interactive tree diagram. It uses d3.tree layout with d3.linkHorizontal to render the connecting paths, while d3.zoom enables panning and scaling of the SVG view. Country names appear as text labels with font sizes decreasing by depth level. The data comes from a JSON file containing the nested geographic hierarchy. Text styling employs the Playfair Display font with white shadows for readability.

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 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.
