A cheerful yellow smiley face is drawn in an SVG canvas using D3 v5, with black outlined eyes and a mouth. The example demonstrates basic SVG shape creation and manipulation through D3’s `select` and `append` methods. Two rectangular eyebrows animate vertically using `transition().duration()`, moving up and then back down over two seconds each. The code also utilizes D3’s `arc` path generator to construct the mouth, showing fundamental drawing and animation capabilities on a static 900x600 canvas.
