1. Initial state: A butterfly tree is a symmetrical fractal pattern resembling the shape of a butterfly. It is composed of interconnected branches, each branching into smaller sub-branches.

2. Web Formation: The transformation of the butterfly tree into a web begins as the branches near the center start to curve and bend toward each other. This curvature gradually tightens, pulling the branches closer and creating a web-like structure.

3. Merging Branches: As the branches continue to curve inwards, they eventually merge and fuse with each other, creating a continuous network of interconnected strands. The original tree structure becomes obscured, and the web pattern becomes more pronounced.

4. Central Hub: At the center of the web, where the branches originally met, a pronounced hub or focal point emerges. This central hub acts as the connecting point for all the strands of the web, further reinforcing the web-like structure.

5. Intricate Patterns: As the transformation progresses, the web becomes increasingly complex and intricate. The interwoven strands create a mesmerizing pattern of interlaced lines, reminiscent of a spider's web. The original butterfly shape is now completely lost, replaced by the intricate web structure.

6. Completion: The final stage presents a fully realized web structure. The butterfly tree has completely transformed into a web, devoid of any resemblance to its initial form. The central hub serves as the central focal point, radiating delicate strands that weave and interconnect, creating a captivating and symmetrical web pattern.
