A hierarchical tree layout displays the countries of the world organized by continent and subregion, with each country as a leaf node. The visualization uses `d3.tree` and `d3.hierarchy` to compute the layout from a nested JSON structure, rendering curved links with `d3.linkHorizontal`. Text labels position nodes with font sizes inversely scaled by depth inside an SVG, while `d3.zoom` enables panning and zooming the entire tree.

Fork of World Countries Tree

This visualization presents a hierarchical tree of world countries, organized by continent and subregion, with each country labeled as a leaf node. The tree layout positions nodes horizontally, with links drawn as curved paths and text labels scaled by depth. Built with D3 v5, it uses `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal` to compute and render the layout, while a zoom behavior enables panning and scaling of the SVG canvas. The data is loaded from a JSON file, and the styling uses a serif font with orange link strokes.

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

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 displays a hierarchical tree of world countries, organized by continent and subregion. It uses a left-to-right dendrogram layout, with each country shown as a text label at the leaf level. The code employs d3.tree and d3.hierarchy to compute the layout, d3.linkHorizontal for the curved connecting paths, and d3.zoom for panning and zooming the SVG canvas. Font size decreases with depth, and the data originates from a structured JSON file.

Fork of World Countries Tree

A collapsible tree visualization displays the hierarchical structure of world countries, organized by continent and subregion. The code uses D3 v5’s `stratify` to convert a flat CSV dataset into a hierarchy, then applies the `tree` layout and `linkHorizontal` to render curved links. Nodes are labeled with country names, with font size decreasing by depth. The SVG output supports panning and zooming via `d3.zoom`, and links and text are styled with custom CSS including a serif font and text shadows.

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 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.
