This animation depicts a stylized, two-stranded DNA helix constructed from a sequence of circles connected by smooth, colored paths. The parallel strands oscillate horizontally, and the connecting rungs are rendered as thick line segments, creating a simplified molecular representation. The visualization is built with D3 version 7, using its `line` generator and the `.join()` operation to efficiently update SVG circles, paths, and lines at 60 frames per second via `setInterval`. Two independently timed sine-wave functions drive the positional data for each strand.
