This visualization displays a hierarchical tree of world countries, organized by region and subregion, using a horizontal dendrogram layout. The tree structure is rendered with SVG, showing parent-child relationships through curved link paths and text labels that decrease in font size with depth. The code uses D3 v5’s `tree()`, `hierarchy()`, and `linkHorizontal()` to compute and draw the layout, with `d3.zoom()` enabling pan and zoom interactions. Data comes from a local `data.json` file containing nested country groupings.

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, 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 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 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

This visualization displays a hierarchical tree of world countries, organized by region and subregion, using a horizontal node-link layout. The code renders the structure with SVG paths and text labels, applying D3’s `tree()` layout, `hierarchy()`, `linkHorizontal()`, and `zoom()` for pan and zoom interactions. Data is loaded from a JSON file containing nested country groupings, with label font size decreasing by depth. The visualization uses a custom Playfair Display font and subtle text shadows for readability.

Fork of World Countries Tree

This visualization shows a hierarchical tree of world countries, organized by continent and subregion, with each node labeled by country name. The tree layout positions nodes vertically by depth, and horizontal links connect parent and child nodes. The visualization uses D3 v5’s `tree` layout, `hierarchy` function, and `linkHorizontal` generator to compute and draw the structure. Text labels scale in font size inversely with depth, and the entire tree can be panned and zoomed via D3’s `zoom` behavior. Data comes from a JSON file with nested country groupings.

Fork of World Countries Tree

This interactive visualization displays a hierarchical tree of world countries organized by continent and subregion, with each leaf node labeled by country name. The layout uses a horizontally-oriented tree structure where nodes are positioned based on depth and rendered as text elements with varying font sizes. Built with D3 v5, the visualization employs `d3.tree()` for layout computation, `d3.hierarchy()` for data structuring, and `d3.linkHorizontal()` for generating curved link paths between nodes. The SVG rendering includes zoom functionality via `d3.zoom()`, with data loaded from a JSON file containing the hierarchical country classification.

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.
