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 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 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

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

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 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.

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

This visualization shows the hierarchical structure of world countries, organized by continent and subregion, as a horizontal tree layout. It uses d3.tree and d3.hierarchy to compute the layout, and d3.linkHorizontal to draw the connecting paths. Node labels are positioned along the tree, with font size scaling by depth, and a d3.zoom behavior allows panning and zooming the SVG view. The rendering uses SVG elements styled with a green stroke and a Playfair Display font, with data loaded from a local JSON file.

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.
