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. The visualization uses D3’s `select` and `attr` methods to access and modify SVG elements, while the `d3-force` library’s `forceSimulation` API is initialized with node data, though the simulation is immediately stopped. The code imports `arc` from D3, and the SVG canvas is 960 by 500 pixels. The embedded video illustrates the intended animated behavior, while the static page presents the underlying code structure.
