This D3 v7 visualization animates three shape-based silhouettes—a star, a tree, and a skyline—constructed from connected line segments. A central black star is surrounded by five smaller gold stars that float continuously, while the tree and skyline use distinct colors. The code uses D3's `select`, `join`, and `transition` APIs to draw lines, apply hover effects, and animate expansion from the center, with a visible star-orbit animation.
