This visualization presents a hierarchical tree of world countries, organized by continent and subregion, using a horizontal dendrogram layout. The code employs `d3.tree()` and `d3.hierarchy()` to compute node positions from a JSON data file, with `d3.linkHorizontal()` generating smooth curved links between parent and child nodes. Interactive zooming is enabled through `d3.zoom()`, allowing users to explore the full dataset. Node labels are rendered as SVG text elements with font sizes that decrease per depth level, while paths are styled with a teal stroke and Playfair Display typography.

Fork of World Countries Tree

This visualization displays a hierarchical tree of world countries organized by continent and subregion, using a left-to-right dendrogram layout. The D3 v5 code loads hierarchical JSON data and renders it as SVG paths and text labels. It applies a `tree` layout with `linkHorizontal` for curved connections, supports zooming via `d3.zoom`, and uses the Playfair Display font for country names.

Fork of Fork of World Countries Tree

This visualization presents a hierarchical tree of world countries, organized by continent and subregion, using a branching layout that expands from left to right. The data is loaded from a JSON file, and the tree structure is rendered as SVG paths and text labels. The code uses D3 v5’s `tree()` layout, `hierarchy()`, and `linkHorizontal()` to compute the layout and draw the connecting links. Users can pan and zoom the entire diagram via the `zoom()` behavior, with text sizing decreasing at deeper levels to fit the hierarchy.

Fork of World Countries Tree

This visualization shows a hierarchical tree of world countries, organized from continents down to subregions and individual nations, using a horizontal dendrogram layout. Labels appear at each node, with font size decreasing by depth to emphasize higher-level groupings. The implementation uses D3 v5’s `d3.hierarchy`, `d3.tree`, and `d3.linkHorizontal` to compute the layout and draw SVG paths, while `d3.zoom` enables panning and zooming. Styling relies on a Playfair Display font and teal connection lines, with data loaded from a local JSON file.

Fork of World Countries Tree

This visualization displays a hierarchical tree of world countries, organized by continent and subregion, with the root labeled "World" and leaf nodes representing individual nations. The layout uses a tidy tree algorithm to position nodes, with horizontal links rendered as smooth curves. The SVG rendering employs D3 v5’s `tree`, `hierarchy`, and `linkHorizontal` methods, while pan and zoom interactions are enabled via the built-in `zoom` behavior. Text labels are sized inversely to node depth, creating a clear visual hierarchy.

Fork of World Countries Tree

This visualization shows the hierarchical structure of world countries organized by continent and subregion, with each country name displayed as a text label connected by branching paths. The tree layout uses `d3.tree` and `d3.hierarchy` to compute node positions, while `d3.linkHorizontal` draws the curved links. The SVG rendering supports pan and zoom via `d3.zoom`, and text styling uses a Playfair Display font with white shadows for readability. Data comes from a JSON file containing the nested geographic hierarchy.

Fork of World Countries Tree

This visualization displays a hierarchical tree of world countries organized by continent and subregion, with each leaf node representing a country rendered as text. Using the D3 v5 tree layout, the code converts nested JSON data into a horizontal dendrogram, connecting parent-child relationships with curved paths generated by `linkHorizontal`. Text nodes are positioned via `d3.hierarchy` and styled with font sizes decreasing by depth. The SVG output supports pan and zoom through D3’s `zoom` behavior, while labels include white text-shadows for readability against the teal link strokes.

Fork of World Countries Tree

This visualization shows a hierarchical tree of world countries, organized by continent and subregion, with country names displayed at varying font sizes based on their depth in the tree. It uses D3 v5 with the `d3.tree` layout and `d3.hierarchy` to compute the node positions, while `d3.linkHorizontal` generates the curved connecting paths. The SVG rendering supports zooming and panning through D3's `d3.zoom` behavior, and the data comes from a local `data.json` file containing the nested geographic structure.

Fork of World Countries Tree

This visualization displays the hierarchical structure of world countries, grouped by continent and subregion, using a tree layout. It renders a horizontal dendrogram where each country appears as a text label, with font size decreasing at deeper levels. The visualization uses d3.hierarchy and d3.tree to compute the layout, with d3.linkHorizontal generating the curved connecting paths. Users can pan and zoom the SVG via d3.zoom. The data comes from a JSON file containing nested geographic regions, and the styling uses a Playfair Display font with text shadows for readability.
