This example visualizes the hierarchical relationships between world regions, subregions, and countries using a tree layout. The code employs `d3.hierarchy`, `d3.tree`, and `d3.linkHorizontal` to compute and draw the node links as SVG paths. Text labels are positioned according to tree depth, with font size decreasing for deeper levels, and `d3.zoom` enables panning and zooming. The data structure in `data.json` organizes countries under continents and subregions, rendered with a white text shadow for readability.

World Countries Hierarchy

This example presents the hierarchical structure of world countries using a tree diagram. The visualization organizes countries by continent and sub-region, displaying the data from `data.json` as horizontally laid-out nodes connected by link paths. Rendered as an SVG, the code utilizes the d3 library's `hierarchy`, `tree`, and `linkHorizontal` APIs to compute the layout and draw the connections. Text labels, styled with a Roboto font, are positioned using the nodes' calculated coordinates, and a zoom interaction is enabled via the `zoom` API.

World countries hierarchy

This visualization displays the hierarchical structure of world countries, organized by continent and subregion. It uses a horizontal tree layout rendered as SVG, with connecting paths and country labels. The code employs `d3.hierarchy`, `d3.tree`, and `d3.linkHorizontal` to compute positions and draw links, while `d3.zoom` enables interactive panning and scaling. Text sizes decrease with depth, and the data comes from a JSON file.

World Countries Hierarchy

This example visualizes the hierarchical structure of world countries, organized by continent and subregion, using a static tree layout with horizontal links. The SVG rendering uses D3 v5’s `hierarchy` and `tree` layouts, with `linkHorizontal` for the connecting paths. Node labels are sized proportionally to their depth in the hierarchy, and circles mark each country or region. The visualization supports zooming and panning through D3’s `zoom` behavior. Data is loaded from a local `data.json` file containing the nested geographic classification.

World Countries Tree

This example shows a hierarchical tree of world countries organized by continent and subregion. The layout uses D3’s `tree()` and `hierarchy()` functions to compute node positions, with curved `linkHorizontal()` paths connecting parent and child nodes. Labels display each country’s full name, with font size decreasing by tree depth. The visualization supports pan and zoom through D3’s `zoom()` behavior, applied to a group element. Data comes from a static `data.json` file, and all rendering is done with SVG elements styled via external CSS.

World Countries Hierarchy

This visualization displays the hierarchical relationships between world regions, subregions, and countries using a horizontal tree layout. The data is structured as a nested JSON hierarchy, with nodes representing continents, regions, and individual nations. The code uses D3 v7’s `tree()` layout and `linkHorizontal()` generator to position and draw the connecting paths, while node labels are rendered as SVG text elements with sizes scaled by node depth. A zoom behavior is applied to the SVG container for panning and scaling.

World Countries Hierarchy

A hierarchical tree visualization displays the world's countries organized by continent and subregion. The visualization uses D3 v5's `tree` layout with `linkHorizontal` paths to connect parent and child nodes. Text labels for each country are positioned according to the layout's x and y coordinates, with font sizes scaling logarithmically based on depth. The SVG rendering supports zooming and panning through D3's zoom behavior, and the data originates from a JSON file containing the nested geographic hierarchy.

World Countries Tree

This example presents the hierarchical structure of world countries organized by continent and subregion as a tree diagram. The visualization uses a horizontal tree layout from D3 v5, with nodes representing geographic regions and countries, connected by curved links. Users can pan and zoom the entire structure through D3’s zoom behavior. The code builds the layout with `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal`, rendering text labels with font sizes that decrease with depth. Data is loaded from a local JSON file, and the SVG output features a custom serif font and distinct stroke color.

World Countries Tree

This visualization shows the hierarchical structure of world countries organized by continent and subregion, with each country labeled as a leaf node in a tidy tree layout. The tree radiates horizontally from a root node, with font sizes decreasing at deeper levels and country names displayed after their parent regions. Using D3 v5, the implementation applies `d3.tree()` and `d3.hierarchy()` to compute node positions, `d3.linkHorizontal()` to generate curved link paths, and SVG rendering with pan-and-zoom support via `d3.zoom()`. The data comes from a pre-structured JSON file, and text elements include a glow effect via CSS `text-shadow` for readability.
