This interactive tree diagram displays the hierarchical organization of world countries, grouped by continent and subregion, using a dataset from the UN (data.json). The visualization employs D3 v5’s `tree` layout and `hierarchy` function to compute node positions, with `linkHorizontal` drawing the connecting paths. Node labels are not rendered in this example; instead, a steelblue background rect is drawn, and the chart is sized to fill the viewport via `document.body.clientWidth/Height`. The underlying data is static JSON, while a separate CSV file provides population figures, though these are not currently linked or displayed.

World Countries Tree

This visualization shows the hierarchical structure of world countries organized by continent and subregion, displayed as a horizontal tree diagram. The layout derives from a JSON dataset containing the United Nations’ geographical groupings, with text labels at each hierarchy level sized by depth. The implementation uses D3 v5’s `tree` and `hierarchy` layouts to compute positions, `linkHorizontal` for the connecting paths, and `zoom` to enable panning and scaling. All rendering is done as SVG elements within a `g` container, styled with Playfair Display fonts and teal-colored links.

world countries tree

This visualization shows the hierarchical organization of world countries, arranged as a horizontal tree with continents branching into subregions and then individual nations. The layout positions child nodes to the right of their parent categories, with text labels displayed at varying font sizes based on depth level. Built with D3 v5, the code uses `d3.tree()` and `d3.hierarchy()` to compute the tree structure, `d3.linkHorizontal()` for the connecting paths, and loads country data from a JSON file. The visualization is rendered as SVG, with paths and text elements styled using CSS.

World Countries Tree

This visualization displays a hierarchical tree of world countries, organized by continent and subregion. It shows the structural relationships between geographical groupings, with each node labeled by name. The chart uses D3.js v5's `tree` layout and `hierarchy` functions to compute the graph, and `linkHorizontal` paths to draw the connecting lines. Data is loaded from a JSON file, and the visualization supports interactive zooming via a custom `zoom` event, with labels styled using the Playfair Display font.

world countries tree

This visualization displays a hierarchical tree of world countries, organized by continent and subregion, with the root node at "World." The layout uses a horizontal tree structure in which continent and subregion branches extend outward to individual country names. Rendered in an SVG canvas, the chart connects parent nodes to children with curved paths, and each country appears as a text label. The implementation relies on the D3.js library, specifically using the `tree`, `hierarchy`, and `linkHorizontal` functions to compute the layout and generate edge paths, while loading the hierarchical data from a local JSON file.

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()` and `hierarchy()` functions to compute node positions and draws curved links with `linkHorizontal()`. Static labels are placed at each node, and the data comes from a local `data.json` file containing the nested geographic classification.

World Countries Tree

This hierarchical tree visualization displays the structure of world countries, grouped by continent and subregion. Country names are rendered as text nodes, connected by horizontal link paths to reveal the geographic taxonomy. The visualization uses D3 v5’s `tree` layout, `hierarchy`, and `linkHorizontal` functions to position nodes and draw edges, with interactive zooming enabled via `d3.zoom`. Data comes from a JSON file containing the nested world regions, with text styling applied for readability.

World Countries Tree

This visualization displays the hierarchical structure of world countries, organized by continent and subregion. It uses a horizontal tree layout, with each country name rendered as a leaf node and connections drawn as curved links. The code employs D3 v5’s `tree()` layout, `hierarchy()`, and `linkHorizontal()` path generator to position nodes and draw edges in SVG. Data comes from a local `data.json` file containing the nested geographic grouping.

World Countries Tree

This interactive visualization presents the hierarchical structure of world countries, organized by continent and subregion. It uses a horizontal tree layout, with the root node on the left and leaf nodes (countries) extending to the right. The D3.js library (v5) computes the tree layout via `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal`. Pan and zoom are handled through `d3.zoom`. The data is loaded from `data.json` and rendered as SVG paths and text elements, with node labels sized by depth.
