Fork of HTML Starter

This example displays a simple SVG face composed of a yellow circle with a black outline, two black eye circles, and a black arc for a mouth, all centered on a 500 by 500 pixel canvas. The page uses raw HTML with embedded CSS to center the content and scale the text, and inline SVG elements (circle and arc) for the drawing. No JavaScript libraries are involved; the markup is static, with the styling and geometry defined directly in the SVG attributes. The rendering relies entirely on the browser’s native SVG support.

Fork of World Countries Tree

This visualization displays a hierarchical tree of world countries organized by continent and subregion, with each leaf node representing a country rendered as text. Using the D3 v5 tree layout, the code converts nested JSON data into a horizontal dendrogram, connecting parent-child relationships with curved paths generated by `linkHorizontal`. Text nodes are positioned via `d3.hierarchy` and styled with font sizes decreasing by depth. The SVG output supports pan and zoom through D3’s `zoom` behavior, while labels include white text-shadows for readability against the teal link strokes.

World Countries Tree

This visualization shows the hierarchical structure of world countries organized by continent and subregion, with each country as a leaf node in a tree layout. The example uses D3 v5 with the `cluster` layout and `hierarchy` function to process the nested JSON data, while `linkHorizontal` generates curved paths between parent and child nodes. The resulting SVG renders all connections as black lines on a white background, filling the entire browser viewport.

Fork of Cheap Tricks for Interaction

This example shows an interactive world map rendered with SVG paths. It presents countries in light green against a blue spherical background, and hovering over a country turns it red. The visualization uses a D3 geoNaturalEarth1 projection with a geoPath generator to draw continents from a world-atlas TopoJSON dataset. The code imports from d3.js v5 and TopoJSON, and it handles zooming and panning through D3’s zoom interaction, which applies a transform to the map group on zoom events.
