Fork of World Countries Tree

This tree visualization displays the hierarchical structure of world countries, with nodes labeled by country identifiers and connected by curved paths. The layout uses `d3.tree` and `d3.hierarchy` to compute positions, while `d3.linkHorizontal` generates the links. The SVG renders with a green stroke for paths and serif text, with font size decreasing by node depth. The visualization supports pan and zoom through `d3.zoom`, applied to a background rectangle. Data is loaded from a local `data.json` file, and the code uses D3 v5 via ES modules.

Drawing SVG Shapes with D3

This example contrasts hand-written SVG markup with D3-generated SVG for drawing a simple bar shape. It shows a static green rectangle created directly in HTML using the `<rect>` element, and an identical rectangle produced dynamically via D3’s selection and append methods. The page uses `d3.select`, `append`, `attr`, and `style` to construct and style the SVG node in the DOM. The code relies on D3 v7 loaded from a CDN and does not use any data binding or scales.

Hello HTML

This example displays two yellow circles with black outlines and a green arc, all rendered as SVG elements. The page uses React 18.2.0 through a CDN, along with d3.arc to construct the arc path. A d3.select call appends a group and places the arc, while the circles are drawn directly in the HTML. The visualization demonstrates basic SVG shape rendering combined with D3’s arc generator.
