This visualization displays the hierarchical structure of world countries organized by continent and region, rendered as a horizontal tree layout. The D3.js code uses `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal` to compute node positions and draw curved links from the hierarchical JSON data. Each country name appears as SVG text with font size decreasing by depth, while pan and zoom are enabled through `d3.zoom` on the entire SVG group.

World Countries Tree

This visualization displays the hierarchical structure of world countries, organized by continent and region, as a horizontal tree diagram. The layout uses d3.tree to calculate node positions and d3.hierarchy to process the nested JSON data structure. Links are rendered as horizontal curved paths via d3.linkHorizontal, while text labels use a serif font and decrease in size with depth. The SVG canvas supports zooming and panning through d3.zoom, with styling handled by CSS.

World Countries Tree

This visualization displays the hierarchical structure of world countries, organized by continent and region as a horizontal tree diagram. The D3.js v5 code uses `d3.hierarchy` and `d3.tree` to compute node positions, with `d3.linkHorizontal` generating curved link paths between parent and child nodes. Labels show region and country names, with font size decreasing at deeper levels. The SVG canvas supports pan and zoom through the `d3.zoom` behavior, and the styling applies a serif font with contrasting turquoise links against a clean 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 displays the hierarchical structure of world countries organized by continent and subregion, using a D3 tree layout rendered as an SVG. The code applies `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal` to position nodes and draw curved links, with zoom support via `d3.zoom`. Country names appear as text labels sized by depth, and the data comes from a JSON file reflecting geographic classifications.

World Countries Tree

This visualization shows the hierarchical structure of world countries, organized by continent and subregion, as a horizontal tree layout. The data is loaded from a JSON file and rendered as SVG. Using d3.tree, d3.hierarchy, and d3.linkHorizontal, the code draws curved links between nodes and displays country names with font sizes that decrease by depth. The visualization supports zooming and panning via d3.zoom, with a Playfair Display font and teal-colored paths for the 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.

World Countries Tree

This D3.js visualization shows the hierarchical structure of world countries, organized by continent and subregion, using an indented tree layout. The SVG rendering displays country names as text nodes connected by curved paths, with font size decreasing at each depth level to emphasize the hierarchy. The code uses `d3.json` to load the country data, `d3.tree` for layout, `d3.hierarchy` for nesting, and `d3.linkHorizontal` for the link paths. A custom `d3.zoom` event handler enables interactive pan and zoom of the entire visualization.
