Fork of Radial Tree of Countries Hierarchy

This radial tree visualization displays a hierarchical breakdown of world countries by continent and subregion, with each node labeled by name and scaled by depth. The layout uses a D3 cluster layout, projecting nodes in a circular arrangement from a central root. Users can pan and zoom the SVG canvas via d3.zoom. The data, loaded from a JSON file, is structured hierarchically, and the code adapts Curran Kelleher’s original block by adjusting link paths and text rotation for readability.

Fork of Fork of Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by constructing a smiley face whose eyebrows move, driven by loading population data from a CSV file. The visualization uses d3.select to target an SVG element and d3.csv to fetch and parse data.csv, logging the parsed rows to the console. The page is rendered as SVG within a fixed-size viewport, with D3 v5 handling the asynchronous data loading. The code currently only reads the data and does not yet apply it to animate the face.

Fork of Let's Make a Face Part I

This example shows a simple yellow smiley face, constructed from three SVG circles: a large yellow face with a black outline and two smaller black circles for eyes. The face is centered on a 960 by 500 canvas, with the head positioned at the midpoint and the eyes offset horizontally. Rendered directly via inline SVG elements in the index.html file, the code uses no external libraries, relying on basic shape attributes like `cx`, `cy`, `r`, and `stroke-width` to define the visual. The accompanying README notes it is only "half way towards a smiley face," as the mouth is absent.

Fork of Let's make a face with D3.js!

A D3.js visualization renders a yellow smiley face in SVG, centered within a 960 by 500 canvas. The face features a black-outlined circle, two eyes, and an arc-shaped mouth created using D3’s `arc()` generator. The code demonstrates fundamental DOM manipulation by using `d3.select` to target the existing SVG element, then appending groups and shapes with `append` and setting attributes like `r`, `cx`, and `transform`. The eyes are positioned via translation offsets, while the mouth’s path uses an inner and outer radius, with angles specified in radians to define the arc’s sweep.
