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 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.

Fork of World Countries Tree

This visualization shows the hierarchical structure of world countries, organized by continent and subregion, as a horizontal tree layout. It uses d3.tree and d3.hierarchy to compute the layout, and d3.linkHorizontal to draw the connecting paths. Node labels are positioned along the tree, with font size scaling by depth, and a d3.zoom behavior allows panning and zooming the SVG view. The rendering uses SVG elements styled with a green stroke and a Playfair Display font, with data loaded from a local JSON file.

Fork of World Countries Tree

This visualization displays the hierarchical structure of world countries, organized by continent and sub-region, as a horizontal tree diagram. The SVG rendering uses the D3.js library’s `tree` layout, `hierarchy`, and `linkHorizontal` components to position nodes and draw connecting paths. Country names appear as text labels, with font size decreasing at deeper levels, and an interactive `zoom` feature allows users to pan and scale the view. Data is loaded from a local `data.json` file, and the styling is applied via CSS, including a Playfair Display serif font.

Fork of World Countries Tree

This visualization shows the hierarchical structure of world countries, organized by continent and subregion, as a horizontal tree layout. It uses d3.tree and d3.hierarchy to compute node positions, with linkHorizontal for curved connecting paths. The SVG rendering supports zooming and panning via d3.zoom, while text labels display country names with font sizes that decrease by node depth. Data is loaded from a local JSON file, and the styling uses custom CSS with a Playfair Display font and green stroke for links.

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 the nation names rendered as text nodes connected by curved links. It uses a d3.tree layout with a horizontal link generator to position the hierarchy in an SVG canvas, and d3.zoom enables panning and zooming across the full-width and height layout. The data comes from a static JSON file, and the text size decreases with depth to emphasize regional groupings. The code leverages d3.select, d3.hierarchy, d3.linkHorizontal, and d3.event, with custom Playfair Display typography and a stroke color for the paths.

Fork of World Countries Trees

This visualization displays the hierarchical structure of world countries, organized by continent and subregion using a tree layout. The data is loaded from a JSON file and rendered as an SVG with horizontal links connecting parent and child nodes. Using D3 v5’s `tree`, `hierarchy`, and `linkHorizontal` functions, the code positions labels with font sizes decreasing by depth and includes zoom functionality via `d3.zoom`. Country names are styled with a Playfair Display serif font, and the visualization fills the entire browser window.

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.
