This visualization presents a hierarchical tree of world countries organized by continent and subregion, rendered as an interactive SVG. The root node labeled "Blood Group" branches into major regions such as Western Asia and South-Eastern Asia, with country names as leaf nodes. Using D3 v5, the code applies a `d3.tree()` layout and `d3.linkHorizontal()` to draw curved links between parent and child nodes. Panning and zooming are enabled through D3's `d3.zoom()` behavior on the SVG element, with text labels sized dynamically based on depth.

Fork of World Countries Tree

This visualization shows the hierarchical structure of world countries grouped by continent and subregion, rendered as an SVG tree diagram. The d3.tree layout positions nodes based on a JSON dataset containing country and region names, while d3.linkHorizontal draws curved paths between parent and child nodes. Text labels display each geographic entity with font size scaled by depth. The chart supports pan and zoom via d3.zoom, and uses a Playfair Display serif font with a white text shadow for readability.

Fork of World Countries Tree

This interactive visualization displays a hierarchical tree of world countries, organized first by continent and then by subregion. The layout flows horizontally, with larger text for parent nodes and smaller text for child nodes, connected by curved green links. Built with D3 v5, the visualization uses the `d3.tree` layout and `d3.linkHorizontal` path generators to structure the data, while `d3.zoom` enables panning and zooming of the SVG canvas. Text styling supports a serif font with a white shadow for readability.

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 displays a hierarchical tree of world countries, organized by continent and subregion. It uses a D3 tree layout with horizontal links to show the parent-child relationships between geographic groupings, from "World" down to individual nations. The text labels are sized according to depth, with shallower nodes appearing larger. The implementation uses D3 v5’s `tree`, `hierarchy`, and `linkHorizontal` functions to compute the layout and link paths, while a zoom behavior allows panning and scaling of the SVG rendering.

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 shows a hierarchical tree of world countries organized by continent and subregion, with country names displayed at varying font sizes based on depth. The tree layout uses d3.tree with a horizontal link generator (d3.linkHorizontal) to connect parent and child nodes, while d3.zoom enables panning and zooming of the SVG rendering. The data, loaded from a JSON file via d3.json, contains nested geographic groupings, and the text nodes are positioned along the computed tree coordinates with depth-based font scaling.

Fork of World Countries Tree

This visualization displays the hierarchical structure of world countries, organized by continent and subregion. The tree branches from a central root, showing the geographic groupings. The visualization uses the D3.js library with a vertical link layout to connect nodes. The SVG rendering applies a zooming feature and custom styling, with text labels sized based on the tree depth. The data is loaded from a JSON file and rendered using D3's hierarchy and tree layout functions.

Fork of World Countries Tree

A hierarchical tree visualization displays world countries organized by continent and subregion. The data structure nests nations under regional groupings like Southern Asia and Western Asia. Using D3 v5's `d3.tree` layout and `d3.hierarchy`, the example renders SVG paths with rounded corners via a custom link generator. Text labels use a Playfair Display font, with font size scaling by node depth. Users can pan and zoom the entire visualization through D3's `d3.zoom` behavior.
