This visualization shows a hierarchical tree of world countries organized by continent and subregion, with the nation names rendered as text nodes connected by curved links. It uses a d3.tree layout with a horizontal link generator to position the hierarchy in an SVG canvas, and d3.zoom enables panning and zooming across the full-width and height layout. The data comes from a static JSON file, and the text size decreases with depth to emphasize regional groupings. The code leverages d3.select, d3.hierarchy, d3.linkHorizontal, and d3.event, with custom Playfair Display typography and a stroke color for the paths.

Fork of World Countries Tree

This visualization shows a hierarchical tree of world countries organized by continent and subregion, using a collapsible layout where text labels are positioned along branching paths. The tree renders in SVG with zoom and pan capabilities enabled by the d3.zoom interaction. It uses d3.hierarchy to build the structure from a JSON data source, d3.tree to compute the layout, and d3.linkHorizontal to generate curved connector paths. Text size scales inversely with depth, and styling uses the Playfair Display font with a custom CSS shadow effect for readability.

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 node positions, with linkHorizontal for curved connecting paths. The SVG rendering supports zooming and panning via d3.zoom, while text labels display country names with font sizes that decrease by node depth. Data is loaded from a local JSON file, and the styling uses custom CSS with a Playfair Display font and green stroke for links.

Fork of World Countries Tree

This visualization displays the hierarchical structure of world countries, grouped by continent and subregion, using a tree layout. It renders a horizontal dendrogram where each country appears as a text label, with font size decreasing at deeper levels. The visualization uses d3.hierarchy and d3.tree to compute the layout, with d3.linkHorizontal generating the curved connecting paths. Users can pan and zoom the SVG via d3.zoom. The data comes from a JSON file containing nested geographic regions, and the styling uses a Playfair Display font with text shadows for readability.

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 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 a hierarchical tree of world countries, organized by continent and subregion, with each country name displayed as a text label. The tree layout positions nodes horizontally, with links drawn as curved paths in green. The visualization uses D3 v5's `tree` and `hierarchy` functions to compute the layout, `linkHorizontal` for path generation, and `zoom` for pan and zoom interactions. Data is loaded from a JSON file, rendered as SVG, and styled with 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, using a horizontal tree layout. The D3.js code employs `d3.tree` and `d3.hierarchy` to compute node positions, `d3.linkHorizontal` to draw curved connecting paths, and `d3.zoom` to enable pan and zoom interactions. Text labels for each country and region are rendered directly in SVG, with font sizes decreasing by depth level. Data comes from the included `data.json` file, which nests countries geographically.
