This visualization displays a hierarchical tree of world countries organized by continent and region, with a root node labeled "World" branching down to individual nations. The code uses D3 v5's `tree` layout and `hierarchy` function to compute node positions, then renders horizontal links via `linkHorizontal` and country names as SVG text with font sizes scaled inversely by depth. The visualization reads from a data.json file and supports interactive panning and zooming through D3's `zoom` behavior, with a zoom group applied to the entire SVG canvas.

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.

Fork of World Countries Tree

This visualization shows the hierarchical structure of world countries, organized by continent and region, as a horizontal tree diagram. It uses D3 v5’s `tree` layout and `hierarchy` function to position the nodes, with `linkHorizontal` generating the curved connecting paths. The visualization supports zooming and panning via D3’s `zoom` behavior, while node labels are displayed with a font size that decreases with depth. The data comes from a local JSON file, and the SVG text elements include a white text-shadow for readability over the mint-green links.

Fork of World Countries Tree

This visualization renders the hierarchical structure of world countries as a vertical tree, grouping nations by continent and subregion. It shows the nested relationships between continents, regional divisions, and individual countries. The code uses D3 v5’s `tree` layout and `hierarchy` functions to compute node positions, with `linkVertical` generating curved paths for connections. SVG circles and text labels display each node, while the `zoom` behavior enables panning and scaling. Data is loaded from a JSON file, and styling uses the Playfair Display font with color-coded nodes and links by depth.

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 displays a hierarchical tree of world countries, organized by continent and subregion. It uses a D3 tree layout with horizontal links to show the parent-child relationships between geographic groupings, from "World" down to individual nations. The text labels are sized according to depth, with shallower nodes appearing larger. The implementation uses D3 v5’s `tree`, `hierarchy`, and `linkHorizontal` functions to compute the layout and link paths, while a zoom behavior allows panning and scaling of the SVG rendering.

Fork of World Countries Tree

This visualization displays a hierarchical tree of world countries, organized by continent and subregion. Using d3.json to load hierarchical data, it applies the d3.tree layout to calculate node positions and renders the structure as an SVG with linkHorizontal paths for connections and text labels for each country. The tree supports zooming and panning through d3.zoom, with text size varying by depth to emphasize hierarchy levels.

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

This visualization displays the hierarchical structure of world countries, organized by continent and subregion, as an interactive tree diagram. It uses D3 v5’s `tree` layout, `linkHorizontal` generator, and `zoom` behavior on an SVG canvas, with nodes labeled by country names. The data is loaded from a JSON file, and the static layout supports pan and zoom via D3’s zoom event. Text size decreases with node depth to emphasize hierarchy.
