## Diagram Type: Proof Diagram
### Overview
The image is a proof diagram that illustrates the steps involved in proving a mathematical statement using induction. The diagram is divided into several sections, each representing a different step in the proof process.
### Components/Axes
- **Original proof**: The main section of the diagram that outlines the original proof.
- **Trimmend sub-tree**: A section that highlights the part of the proof that has been simplified or trimmed.
- **Induction a as [a']**: A section that shows the induction step, where the statement is proven for a specific case.
- **Synthetic proof**: A section that provides a synthetic proof of the statement.
- **Proof**: A section that summarizes the proof and includes the final result.
