This example displays a hierarchical tree of world countries organized by subregions under an overall "Grades" root node. The visualization renders country names as text labels connected by curved horizontal links, with font size decreasing by depth level. It uses D3 v5’s `tree` layout, `hierarchy`, and `linkHorizontal` generators to compute positions and paths, while the SVG output supports pan and zoom via `d3.zoom`. Data comes from a static JSON file.

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 their depth in the tree. It uses D3 v5 with the `d3.tree` layout and `d3.hierarchy` to compute the node positions, while `d3.linkHorizontal` generates the curved connecting paths. The SVG rendering supports zooming and panning through D3's `d3.zoom` behavior, and the data comes from a local `data.json` file containing the nested geographic structure.

Fork of World Countries Tree

This visualization shows the hierarchical structure of world countries organized by continent and subregion, with each country name displayed as a text label connected by branching paths. The tree layout uses `d3.tree` and `d3.hierarchy` to compute node positions, while `d3.linkHorizontal` draws the curved links. The SVG rendering supports pan and zoom via `d3.zoom`, and text styling uses a Playfair Display font with white shadows for readability. Data comes from a JSON file containing the nested geographic hierarchy.

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 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.

Fork of World Countries Tree

This visualization displays the hierarchical structure of world countries, organized by continent and subregion, as an interactive tree diagram. It uses D3 v5’s `tree` layout, `linkHorizontal` generator, and `zoom` behavior on an SVG canvas, with nodes labeled by country names. The data is loaded from a JSON file, and the static layout supports pan and zoom via D3’s zoom event. Text size decreases with node depth to emphasize hierarchy.

Fork of World Countries Tree

This visualization displays a hierarchical tree of world countries organized by continent and subregion, with each leaf node representing a country rendered as text. Using the D3 v5 tree layout, the code converts nested JSON data into a horizontal dendrogram, connecting parent-child relationships with curved paths generated by `linkHorizontal`. Text nodes are positioned via `d3.hierarchy` and styled with font sizes decreasing by depth. The SVG output supports pan and zoom through D3’s `zoom` behavior, while labels include white text-shadows for readability against the teal link strokes.

Fork of World Countries Tree 002

This example shows the hierarchical structure of world countries, organized by continent and subregion, as a vertical tree diagram. The visualization uses a D3 tree layout to compute node positions and renders paths with `d3.linkVertical` for connecting links. Text labels display country names with font sizes scaled by depth. The SVG rendering supports zooming and panning through the `d3.zoom` API. Data is loaded from a local JSON file using `d3.json`, and the code relies on D3 v5's `select`, `tree`, `hierarchy`, and `event` modules.

Fork of World Countries Tree

This example presents a hierarchical tree visualization of countries organized by continent and subregion, with the world at the root. The tree uses horizontal links and text labels whose font size decreases with depth, displaying all country names in a readable layout. The visualization supports pan and zoom via the d3.zoom interaction, applying the transform to a group element. The code builds the layout with d3.tree and d3.hierarchy, renders links using d3.linkHorizontal, and loads the hierarchical data from a JSON file.
