This interactive visualization presents a hierarchical tree of world countries organized by continent and subregion, rendered as a horizontal dendrogram using D3.js v5. The code loads hierarchical JSON data via `d3.json` and applies `d3.tree` layout with `d3.hierarchy` to position nodes, while `d3.linkHorizontal` generates curved paths for the connections. Text labels display country names with font sizes scaled by depth, and a `d3.zoom` behavior enables pan and zoom interactions. The SVG rendering uses a custom font and subtle text shadows to improve readability.

World Countries Tree

This interactive visualization presents a hierarchical tree of world countries, organized by continent and subregion, with the country names displayed as text at varying font sizes based on their depth. The D3 v5 code uses `d3.tree()` and `d3.hierarchy()` to compute the layout, while `d3.linkHorizontal()` generates curved connecting paths between parent and child nodes. Pan and zoom functionality is implemented through `d3.zoom()`, allowing users to explore the data loaded from a JSON file. The SVG rendering uses a green stroke for the links and a serif font for the labels.

World Countries Tree

This interactive visualization displays the hierarchical structure of world countries organized by continent and subregion, rendered as an indented tree layout. It uses D3.js v5 with the `tree`, `hierarchy`, and `linkHorizontal` APIs to compute positions and draw links, along with `zoom` and `event` for pan-and-zoom interaction. The data is loaded from `data.json` via `json()`. Node labels show country names with font size decreasing by depth, and the SVG output uses a teal stroke for connecting paths.

World Countries Tree

This visualization shows the hierarchical structure of world countries, organized by continent and subregion, as a node-link tree diagram. Built with D3 v5, it uses the `d3.tree` layout and `d3.hierarchy` to process the JSON data, while `d3.linkHorizontal` generates the curved connection paths. Text labels display each country with font sizes scaled by node depth, and the interaction model adds panning and zooming via `d3.zoom`. The SVG rendering employs the margin convention and a custom font, with subtle text shadows for readability.

World Countries Tree

This interactive visualization displays the hierarchical structure of world countries organized by continent and subregion using a tree layout. The D3.js v5 code loads geographic data from a JSON file and renders it as an SVG with horizontal links connecting parent and child nodes. Text labels show country names with font sizes that decrease at deeper hierarchy levels, while zoom functionality allows users to explore the full tree structure. The visualization uses the `tree` layout, `linkHorizontal` path generator, and D3's zoom behavior for panning and scaling.

World Countries Tree

This visualization shows a hierarchical tree of world countries, organized by continent and subregion, with the country names displayed as text labels. The tree layout uses `d3.tree` and `d3.hierarchy` to position nodes, while `d3.linkHorizontal` generates curved paths for the connections. The SVG rendering includes zoom functionality via `d3.zoom`, allowing interactive pan and scale. Data is loaded from a JSON file containing geographical groupings, and text styling uses the Playfair Display font with font sizes that decrease with node depth.

World Countries Tree

This interactive visualization displays the hierarchical structure of world countries, organized by continent and subregion, using a horizontal tree layout. It loads country data from a JSON file and renders it as an SVG with D3’s `tree` and `hierarchy` functions, connecting nodes with `linkHorizontal` paths. Text labels scale in font size by depth, and the entire view can be panned and zoomed via D3’s `zoom` handler applied to a group element.

World Countries Tree

This interactive tree diagram displays the hierarchical structure of world countries, organized by continent and subregion, with text labels rendered at varying sizes based on depth. The visualization uses the D3.js v5 `tree` layout with a `linkHorizontal` path generator for curved connections, and implements a `zoom` behavior for panning and scaling. Data loads from a static JSON file, and the SVG rendering applies custom font styling via CSS, including Quicksand and Playfair Display typefaces.
