This visualization shows the hierarchical structure of world countries, organized by continent and subregion, using an expandable tree layout. The data is loaded from a local JSON file and rendered as SVG paths and text labels. The code uses d3.hierarchy and d3.tree to compute the layout, d3.linkHorizontal to draw the connecting links, and d3.zoom to enable panning and zooming. Node labels are positioned along the tree, with font sizes decreasing at deeper levels, and text shadows improve readability over the green link lines.

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, 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 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 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 shows the hierarchical structure of world countries organized by continent and subregion, displayed as a horizontal tree layout. The D3 v5 code loads hierarchical JSON data and renders it as an SVG using d3.tree, d3.hierarchy, and d3.linkHorizontal for the curved links. Text labels show country names with font sizes scaled by depth, while d3.zoom enables panning and zooming on the interactive graphic.

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 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 presents the hierarchical structure of world countries organized by continent and subregion, rendered as a horizontal tree layout. The geographic data is loaded from a local JSON file and displayed using SVG elements. Built with D3 v5, the code applies `tree()` layout, `linkHorizontal()` for curved edges, and `zoom()` for panning and scaling. Text labels use a Playfair Display font, with font size decreasing by depth level to emphasize hierarchy.
