This visualization presents the hierarchical structure of world countries organized by continent and subregion, using a tree layout that branches from a central “World” node. Country names appear at varying font sizes based on their depth in the hierarchy, with linking paths connecting parent and child nodes. The implementation uses D3 v5’s `tree`, `hierarchy`, and `linkHorizontal` functions to compute the layout, while `zoom` enables interactive panning and scaling. Data is loaded from a JSON file, and the SVG rendering applies a custom Playfair Display font with white text shadows for readability.

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 the hierarchical structure of world countries, organized by continent and subregion, as a horizontal tree diagram. It uses D3 v5’s `tree()` layout and `hierarchy()` to compute node positions, with `linkHorizontal()` drawing curved paths between parent and child nodes. Each country name is rendered as SVG text, with font size decreasing by depth. The view supports zooming and panning via D3’s `zoom()` behavior, applied to a containing `<g>` element. Data is loaded from a local `data.json` file, and styling uses 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.

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 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 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. The tree diagram lays out nodes horizontally, with continents as the top level and individual countries as the final leaves. The code uses `d3.tree` for layout, `d3.hierarchy` to parse the JSON data, and `d3.linkHorizontal` to generate the curved connecting paths. Text size scales based on the node’s depth, and the SVG rendering supports pan-and-zoom interaction through the `d3.zoom` event handler. The data is loaded from `data.json` and styled with Playfair Display typography.
