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 the hierarchical structure of world countries, organized by continent and subregion, with all branches originating from a single "World" root node. The tree layout uses vertical curved links to connect parent and child nodes, with country names displayed at varying font sizes based on their depth in the hierarchy. Built with D3 v5, the code employs `d3.tree()`, `d3.hierarchy()`, and `d3.linkVertical()` to compute and render the layout, while `d3.zoom()` enables interactive panning and scaling of the SVG graphic. The data comes from a local JSON file containing the nested geographic classification.

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 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 visualization displays the hierarchical structure of world countries, organized by continent and subregion, using a horizontal tree layout. The D3.js code employs `d3.tree` and `d3.hierarchy` to compute node positions, `d3.linkHorizontal` to draw curved connecting paths, and `d3.zoom` to enable pan and zoom interactions. Text labels for each country and region are rendered directly in SVG, with font sizes decreasing by depth level. Data comes from the included `data.json` file, which nests countries geographically.

Fork of 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 v5’s `tree` layout, `linkHorizontal` generator, and `zoom` behavior on an SVG canvas, with nodes labeled by country names. The data is loaded from a JSON file, and the static layout supports pan and zoom via D3’s zoom event. Text size decreases with node depth to emphasize 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 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 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.
