A hierarchical tree visualizes the structure of world countries grouped by continent and subregion. The layout uses `d3.tree` and `d3.hierarchy` to position nodes, with `d3.linkHorizontal` generating curved link paths. Text labels display country names with font size decreasing by depth. Pan and zoom functionality is implemented via `d3.zoom`. Data comes from a local `data.json` file, rendered as SVG with a teal stroke and Playfair Display font.

World Countries Tree

A hierarchical tree visualizes the geographic structure of world countries, branching from continents into subregions and individual nations. The layout renders as a tidy tree using `d3.tree` and `hierarchy`, with horizontal links generated by `linkHorizontal` and SVG paths. Text labels appear at each node, with font size scaling by depth. The visualization supports pan and zoom interactions via `d3.zoom`, applied to a grouped SVG element. Data comes from a local `data.json` file, and the styling uses the Playfair Display font with text shadows for readability.

World Countries Tree

This visualization shows a hierarchical tree of world countries, organized by continent and subregion, with the country names displayed as text labels. The tree layout uses `d3.tree` and `d3.hierarchy` to position nodes, while `d3.linkHorizontal` generates curved paths for the connections. The SVG rendering includes zoom functionality via `d3.zoom`, allowing interactive pan and scale. Data is loaded from a JSON file containing geographical groupings, and text styling uses the Playfair Display font with font sizes that decrease with node depth.

World Countries Tree

This visualization shows the hierarchical structure of world countries organized by continent and subregion using a tree layout. It displays all countries as text labels connected by curved links, with font size decreasing at deeper levels to indicate hierarchy. The implementation uses D3 v5 with `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal` to compute and draw the layout in SVG. Pan and zoom are enabled via `d3.zoom`, and the data comes from a local `data.json` file containing nested geographic groupings.

World Countries Tree

This interactive visualization displays a hierarchical tree of world countries organized by continent and subregion, rendered as an SVG node-link diagram. The tree layout uses `d3.tree()` and `d3.hierarchy()` to position nodes, while `d3.linkHorizontal()` generates curved links between parent and child nodes. Panning and zooming are enabled through `d3.zoom()`. Data comes from a local JSON file. Text labels show country names, with font size decreasing by depth and a Playfair Display font applied via CSS.

World Countries Tree

This hierarchical tree visualization displays the world’s countries grouped by continent and subregion, using D3’s `d3.tree` layout and `d3.hierarchy` to structure the data. Each node label is rendered as SVG text with font size decreasing by depth, while curved links are drawn using `d3.linkHorizontal`. The chart supports pan and zoom through D3’s `zoom` behavior. Data is loaded from a JSON file, and styling relies on the Playfair Display font.

World Countries Tree

A hierarchical tree visualization displays the world’s countries grouped by continent and subregion, with each node labeled by name. The layout uses D3’s `d3.tree` and `d3.hierarchy` to position nodes, while `d3.linkHorizontal` generates curved connecting paths. Text size decreases with depth, and labels are anchored differently for parent versus child nodes. The SVG rendering supports interactive pan and zoom via D3’s `d3.zoom`, with styling provided by an external stylesheet using the Playfair Display font.
