This example showcases a line drawing of an intricate shape that animates itself onto the screen using a stroke-dash technique. The path is drawn over three seconds with a linear ease. The code uses D3.js version 3.5.6 to select the body, append an SVG, and create the path. It then leverages `path.node().getTotalLength()` and transitions with `attrTween` to animate the `stroke-dasharray` and `stroke-dashoffset` attributes, creating the effect of the line being traced. The underlying data is a static, pre-defined SVG path.
