D3 viz of world countries

World Countries Tree

The visualization displays the hierarchical structure of world countries, organized by continent and subregion, as a radial tree. Country and region names appear as text nodes connected by curved, branching paths, with font size decreasing at deeper levels. The radial layout and linking paths are generated using D3’s `d3.tree`, `d3.hierarchy`, and `d3.linkRadial` APIs. Users can pan and zoom the entire SVG graphic via D3’s `d3.zoom` interaction, which applies a transform to a dedicated zoom group. The data is loaded from a local JSON file.

d3 tree

A radial tree diagram displays a hierarchical dataset of world regions and countries, with nodes positioned by depth and branches extending outward. The visualization uses D3.js v5 to parse the JSON data and render the structure as an SVG, with text labels for each node. The code applies `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal` for layout, and includes zoom interaction via `d3.zoom` to navigate the tree.

D3 World Countries Tree

This visualization displays the hierarchical structure of world countries organized by continent and subregion, using a collapsible tree layout rendered as SVG. The code employs D3 v5’s `tree` layout and `linkHorizontal` generator to draw curved links, with `hierarchy` parsing the nested `data.json` file. Text labels scale in font size based on depth, and a zoom behavior allows panning and scaling via `d3.zoom`. The tree reads from a static JSON dataset and applies Playfair Display typography for readability.

World Countries Tree

This visualization presents the hierarchical structure of world countries organized by continent and subregion, rendered as a radial tree. Each country appears as a text label positioned along circular branches, with curved links connecting parent regions to their children. The code uses d3.tree, d3.hierarchy, and d3.linkRadial to compute layout, while d3.zoom enables interactive panning and zooming. Labels scale in font size based on depth, and the data comes from the provided data.json file with SVG rendering.

world countries tree

This visualization presents a hierarchical tree of world countries, regions, and subregions as an SVG graphic. It uses a D3.js tree layout to position the data in a radial or icicle-like structure, with horizontal links connecting parent and child nodes. The code imports functions like `tree`, `hierarchy`, and `linkHorizontal` from D3 v5, loads the hierarchical data from a local `world.json` file, and renders the connections as SVG `path` elements.

World Countries Tree

This D3.js visualization shows the hierarchical structure of world countries, organized by continent and subregion, using an indented tree layout. The SVG rendering displays country names as text nodes connected by curved paths, with font size decreasing at each depth level to emphasize the hierarchy. The code uses `d3.json` to load the country data, `d3.tree` for layout, `d3.hierarchy` for nesting, and `d3.linkHorizontal` for the link paths. A custom `d3.zoom` event handler enables interactive pan and zoom of the entire visualization.

World Countries Tree

This visualization displays the hierarchical structure of world countries, organized by continent and subregion, using a horizontal tree layout rendered as SVG. The code employs D3 v5’s `tree`, `hierarchy`, and `linkHorizontal` to compute positions and draw curved links, with each node labeled by its region or country name. Users can pan and zoom via `d3.zoom`, with font sizes scaling by node depth. Data comes from a static `data.json` file, and text styling uses the Playfair Display font with white shadows for legibility.

World Countries Tree

This visualization presents a hierarchical tree of world countries organized by continent and region, using a horizontal dendrogram layout where nodes are labeled with country names. The D3.js code loads JSON data, applies a tree layout to compute node positions, and renders curved link paths and text labels with font sizes that decrease with depth. The SVG output supports pan and zoom interactions via d3.zoom, with styling applied through CSS for stroke colors and font family.
