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.

Hfailure

This visualization, titled Hfailure, displays a hierarchical tree representing patient mortality data, showing a decision path from a time threshold to serum sodium levels and ultimately a "Death event." The tree also branches into geographic regions like Western Asia and Eastern Asia, with country-level leaves. Built with D3.js v5, it uses the `tree` layout, `linkHorizontal` for curved paths, and SVG rendering. Text size scales inversely with depth, and a zoom behavior allows interactive panning and scaling. Data is loaded from a local JSON file.
