A hierarchical tree visualization displays the world’s countries, organized by continent and then by subregion (e.g., Southern Asia, Western Asia). Node labels use the `Playfair Display` serif font, with font size decreasing by tree depth. The chart is rendered as an SVG using `d3.tree`, `d3.hierarchy`, `d3.linkHorizontal`, and `d3.zoom`. It loads `data.json` and uses `root.descendants()` to place text labels and generate paths for the links between nodes.

Fork of World Countries Tree

A hierarchical tree visualization displays countries organized by continent and subregion, with the world as the root. The layout positions nodes horizontally by depth, and text size decreases with each level. D3 v5’s `tree` layout, `hierarchy`, and `linkHorizontal` generate the SVG paths and labels, while a `zoom` behavior enables pan and scaling. The data comes from a JSON file, and text styling uses the Playfair Display font.

Fork of World Countries Tree

This visualization renders the hierarchical structure of world countries as a vertical tree, grouping nations by continent and subregion. It shows the nested relationships between continents, regional divisions, and individual countries. The code uses D3 v5’s `tree` layout and `hierarchy` functions to compute node positions, with `linkVertical` generating curved paths for connections. SVG circles and text labels display each node, while the `zoom` behavior enables panning and scaling. Data is loaded from a JSON file, and styling uses the Playfair Display font with color-coded nodes and links by depth.

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 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 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 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 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.
