This visualization displays a hierarchical tree of world countries, organized by continent and subregion, using a left-to-right layout with labeled nodes. It renders country names at varying font sizes based on depth, with horizontal links connecting parent and child nodes. The code uses D3 v5’s `tree`, `hierarchy`, and `linkHorizontal` APIs to compute positions, and applies SVG zooming via `zoom()` on the entire graph. Data comes from a local `data.json` file, and styling uses custom CSS for the serif font and teal link color.

World Countries Tree

This visualization shows a hierarchical tree of world countries organized by continent and subregion, using a left-to-right layout with curved links. It renders country and region names as text nodes, with font size decreasing by depth. Built with D3 v5, it uses `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal` to compute the layout and paths, while `d3.zoom` enables panning and zooming. The data comes from a JSON file, and the SVG output is styled with a custom serif font and teal link strokes.

World Countries Tree

This visualization presents a hierarchical tree of world countries, organized by continent and subregion, using a left-to-right layout. The code employs D3 v5’s `tree` layout and `hierarchy` to structure the JSON data, while `linkHorizontal` draws the connecting paths. Text labels are positioned based on the tree’s node coordinates, with font size varying by depth. Pan and zoom functionality is implemented via D3’s `zoom` behavior on the SVG container. The styling uses a serif font and teal-colored links, with a white text shadow to improve label readability over the paths.

World Countries Tree

This visualization shows the hierarchical structure of world countries organized by continent and subregion. It renders a horizontal tree layout using D3’s `tree()` and `hierarchy()` functions, with countries positioned as leaf nodes. Links are drawn as curved paths via `linkHorizontal()`, while node labels use varying font sizes based on depth. The entire visualization is placed inside a zoomable group, allowing users to pan and scale through the `d3.zoom()` API. Data comes from a local `data.json` file, and the SVG output is styled with custom CSS, including a serif font and green link strokes.

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 subregion, using a left-to-right layout. The code employs D3 v5’s `tree` and `hierarchy` functions to compute node positions, with `linkHorizontal` generating curved paths between parent and child nodes. Each country name is rendered as SVG text, with font size decreasing by depth level, on a zoomable canvas via D3’s `zoom` behavior. The data is loaded from a local JSON file, and the styling uses a Google Font (`Nerko One`) with a white text shadow for legibility.

World Countries Tree

This visualization shows the hierarchical structure of world countries, organized by continent and subregion, as a horizontal tree layout. The code uses D3 v5’s `tree` and `hierarchy` functions to position nodes and `linkHorizontal` to draw connecting paths in SVG. Text labels display country names at varying font sizes based on depth, and the entire view supports zooming via d3.zoom. The data comes from a local JSON file listing regions and their member nations.

It uses a tree layout with horizontal links connecting parent and child nodes, rendered as SVG paths and text labels. The code employs D3 v5’s `tree`, `hierarchy`, and `linkHorizontal` functions to compute positions and generate curved paths, with `zoom` enabling interactive panning. Country names appear with font sizes scaled by depth from `data.json`, which groups nations under regions like Southern and Western Asia, making the geographic taxonomy easily explorable.
