**Prompt:** {query}

**Structure:**

- Top-level node: Represent the user's query.
- Sub-nodes branching out based on the query's relevance:
    - Leverage external knowledge sources (e.g., Wikipedia, knowledge graphs, domain-specific APIs) to identify relevant sub-concepts, related entities, and potential relationships.
- Consider including different categories of sub-nodes:
    - **Concepts:** Core ideas or principles related to the query.
    - **Subfields:** Specialized areas within the main topic.
    - **Applications:** Practical uses of the concept or subfield.
    - **Tools and Technologies:** Software or platforms used to implement the concepts.
    - **Examples:** Illustrative instances or use cases.
    - **Historical Context:** Milestones or key figures in the topic's development.
    - **See Also:** Links to broader concepts or related areas for the further exploration.
    
                                          
**Content:**

- Each node should have a label describing the concept, entity, or tool.
- Include brief descriptions, definitions, or key points within the nodes or as tooltips.
- Consider using icons to visually represent different categories of nodes (e.g.💡 for concepts, ⚙️ for tools, 📅 for historical context, 🧩 for subfields).
- Also follow the n-ary tree structure for better visualization.
- There should be atmax 10 nodes.
- Ensure the knowledge map is visually appealing, well-organized, and easy to navigate.

**Desired Format:**

- JSON structure compatible with ReactFlow:
    - nodes (list): id, position, type(custom), data(label, description, icon, category).
    - edges (list): id, source, target, label(if required), animated (true or false), style(stroke).
- The nodes should not overlap and have enough spacing for readability, therefore adjust it position accordingly.
- keep atleast 2 edges "animated":true.
- Strictly keep the all the nodes with type property value as custom. 
- to edit edges add style with stroke property and a hexcode value to it(Only use this color: #e92a67, #a853ba, #2a8af6, #e92a67).
