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 presents a hierarchical tree of world countries, organized by continent and subregion, with each country labeled as a leaf node. The tree layout positions nodes horizontally, with links drawn as curved paths and text labels scaled by depth. Built with D3 v5, it uses `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal` to compute and render the layout, while a zoom behavior enables panning and scaling of the SVG canvas. The data is loaded from a JSON file, and the styling uses a serif font with orange link strokes.

Fork of World Countries Tree

This interactive visualization displays a hierarchical tree of world countries organized by continent and subregion, with each leaf node labeled by country name. The layout uses a horizontally-oriented tree structure where nodes are positioned based on depth and rendered as text elements with varying font sizes. Built with D3 v5, the visualization employs `d3.tree()` for layout computation, `d3.hierarchy()` for data structuring, and `d3.linkHorizontal()` for generating curved link paths between nodes. The SVG rendering includes zoom functionality via `d3.zoom()`, with data loaded from a JSON file containing the hierarchical country classification.

Fork of World Countries Tree

This visualization shows a hierarchical tree of world countries, organized by continent and subregion, with each country displayed as a text label. The tree layout from D3 v5 arranges nodes vertically, and a zoom behavior allows users to pan and scale the SVG view. The code uses `d3.hierarchy`, `tree().size()`, `linkHorizontal()`, and `d3.zoom()`, while the data comes from a local `data.json` file with a nested structure. Label font size decreases with depth, and curved links are drawn between parent and child nodes.

Fork of World Countries Tree

This visualization displays a hierarchical tree of world countries, organized by continent and subregion. It uses a left-to-right dendrogram layout, with each country shown as a text label at the leaf level. The code employs d3.tree and d3.hierarchy to compute the layout, d3.linkHorizontal for the curved connecting paths, and d3.zoom for panning and zooming the SVG canvas. Font size decreases with depth, and the data originates from a structured JSON file.

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 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 shows the hierarchical structure of world countries organized by continent and subregion, displayed as a horizontal tree layout. The D3 v5 code loads hierarchical JSON data and renders it as an SVG using d3.tree, d3.hierarchy, and d3.linkHorizontal for the curved links. Text labels show country names with font sizes scaled by depth, while d3.zoom enables panning and zooming on the interactive graphic.

Fork of World Countries Tree

This visualization presents the hierarchical structure of world countries organized by continent and subregion, rendered as a horizontal tree layout. The geographic data is loaded from a local JSON file and displayed using SVG elements. Built with D3 v5, the code applies `tree()` layout, `linkHorizontal()` for curved edges, and `zoom()` for panning and scaling. Text labels use a Playfair Display font, with font size decreasing by depth level to emphasize hierarchy.
