Forked from Tree

A compact tree diagram visualizes a four-level hierarchy: the root node "World" branches into continents, which split into countries. The code defines custom node shapes—a blue rounded rectangle for the root, purple circles for continents, and green ellipses for countries—with each node labeled. Using the d3.hierarchy and d3.tree layouts with a vertical link generator, the graph is centered horizontally on the page. The visualization is rendered as SVG with distinct colors per level, sourced from a static inline JavaScript data structure.

Fork of Tree

This visualization presents a world hierarchy as a tree, mapping the root node “World” to four continents—Asia, Europe, Africa, and North America—with two countries as leaf nodes under each continent. Node circles are color-coded by depth: blue for the root, purple for continents, and green for countries, with a legend clarifying the mapping. Using D3 v7, the code employs `d3.tree` and `d3.hierarchy` to compute the layout, then renders horizontal links via `d3.linkHorizontal` and draws circles and labels directly on the SVG, with text placement depending on whether a node has children.

Fork of Tree

A fork of a three-layer D3 v7 tree visualization renders a hierarchical dataset of continents, countries, and cities using SVG. The code builds a vertical tree layout with `d3.hierarchy` and `d3.tree()`, then draws curved links with `d3.linkVertical()`. Node shapes encode depth: rounded rectangles for the root and countries, diamonds for continents, and circles for leaf cities, with a legend explaining each.

Fork of World Countries Tree

This fork of D3's tree diagram displays a hierarchical breakdown of world countries, organized by continent and subregion, with all terminal nodes labeled in a serif font. The visualization is rendered as an SVG, with nodes positioned horizontally based on depth. The code uses D3 v5’s `tree` layout, `hierarchy` and `linkHorizontal` helpers to compute paths, and a `zoom` interaction that rescales the entire drawing on user input. Text size scales inversely with depth, and link paths are styled with a teal stroke.

Fork of World Countries Trees

This visualization displays a hierarchical tree of world countries organized by continent and region, using a horizontal dendrogram layout. The code loads structured geographic data from data.json and employs d3.tree and d3.hierarchy to compute node positions, while d3.linkHorizontal generates the connecting paths rendered as SVG elements. The visualization demonstrates basic D3.js DOM manipulation by appending path elements to an SVG canvas sized to the viewport.

Fork of World Countries Tree

This dendrogram visualizes the hierarchical structure of world countries, organized by continent and subregion, with each node labeled by name. Built with D3 v5, it uses a tree layout and horizontal link generator to position SVG paths and text elements. The visualization supports pan and zoom interaction through D3’s zoom behavior, and applies a Playfair Display font with white text shadows for readability. The hierarchical data is loaded from a JSON file, and font size decreases with depth to indicate level in the tree.

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 example visualizes the hierarchical structure of world countries organized by continent and subregion, with a tree layout that branches from a global root. Built with D3 v5, it reads hierarchical data from a CSV file and renders it as an SVG using `d3.hierarchy`, `d3.tree`, and `d3.linkHorizontal` for smooth curved links. Pan and zoom functionality is enabled via `d3.zoom`, while text labels display country and region names at varying font sizes based on depth. The visualization uses a clean, minimal aesthetic with green connecting paths and serif typography.

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.
