    Generate a detailed flowchart or mind map for the topic/algorithm: "{topic}".

    The output should be in JSON format with the following structure:

    {{

            {{"id": 1, "label": "Start", "level": 0, "shape": "ellipse"}},

        ],
        "edges": [
            {{"from": 1, "to": 2}}
        ]
    }}

    **Important Guidelines:**

    1. **Unique IDs:**  Ensure each node has a unique integer `id`.
    2. **Descriptive Labels:**  Provide clear and concise labels for each node (`"label"`).
    3. **Hierarchical Levels:**  Use `level` to indicate the hierarchy (0 for the top level, 1 for the next level, etc.).
    4. **Node Shapes:**  Choose appropriate shapes using the `shape` field:
        - "ellipse": For start/end nodes
        - "box": For process steps
        - "diamond": For decision nodes
        - "hexagon": For preparation steps
        - "circle": For connectors (if needed)
    5. **Edges:**  Specify connections using the `from` and `to` fields in the `edges` array.
    6. **Flow:** Ensure a logical and easy-to-follow flow.
    7. **Comprehensiveness:**  Include all major steps or concepts.
    8. **Spacing:** Use a minimum horizontal spacing of 200 and vertical spacing of 150 between nodes to prevent overlapping. 
    9. **No Isolated Nodes:** All nodes should be connected in a coherent structure.
    10. **Clear Visualization:** The flowchart/mind map should be visually clear and easily understandable. Avoid overly complex visualizations. 
    11. **Avoid Overlapping:**  Make sure nodes don't overlap with each other (at any level) due to their size or placement.
    12. **Spacing Considerations:** Adjust the spacing between nodes based on the node size and content to ensure adequate readability.

    **Output Format:**
    - Output only the JSON structure, no additional text or explanations.
    - Ensure that the output is correctly formatted and adheres to the provided JSON structure.

Formatting Guidelines:

- Use `#` for main section titles.
- Use `##` for subsections.
- Use `-` for bullet points.
- For **bold text**, wrap the text with double asterisks, e.g., `**important**`.
- For *italic text*, wrap the text with single asterisks, e.g., `*note*`.
- **For tables**, use proper Markdown table syntax with pipes `|` and hyphens `-` for headers.

**Example Table**:
Component	Function
Node 1	Receive user input
Node 2	Process user input
Node 3	Store processed data
Node 4	Retrieve data for display
Node 5	Display data to user


- Keep sentences short and use simple language.
- Focus on the main ideas and avoid unnecessary details.
- Do not include direct error messages or irrelevant information.
