### Summary of "PlantUML 1.2021.3 Справочное руководство по языку"

This documentation provides a comprehensive guide to the PlantUML language, covering various diagram types, features, and usage scenarios. Below is a concise summary of the key points:

---

#### **1. Deployment Diagram**
- **Elements**: Deployment diagrams allow you to represent deployment structures, including elements like `actor`, `agent`, `artifact`, `boundary`, `card`, `circle`, `cloud`, `component`, `control`, `database`, `entity`, `file`, `folder`, `frame`, `hexagon`, `interface`, `label`, `node`, `package`, `queue`, `rectangle`, `stack`, `storage`, and `usecase`.
- **Inline Styling**: Elements can be styled using inline syntax (e.g., `hexagon #aliceblue;line:blue;line.dotted;text:blue`).

---

#### **2. Mathematical Formulas**
- **Integration**: PlantUML supports mathematical formulas using:
- **AsciiMath**: Converts AsciiMath notation to LaTeX.
- **JLatexMath**: Displays LaTeX formulas.
- **Java Compatibility**:
- Java 8 uses Nashorn (deprecated in Java 11).
- Java 11+ requires GraalVM JavaScript Engine to avoid deprecation warnings.
- Add GraalVM dependencies for compatibility.
- **Example**:

  \sum_{i=0}^{n-1} (a_i + b_i^2)

---

#### **3. AWS Library**
- **Features**: The Amazon Labs AWS library provides PlantUML macros, sprites, and includes for AWS services.
- **Resources**:
- GitHub repositories:
- [awslib](https://github.com/plantuml/plantuml-stdlib/tree/master/awslib)
- [AWS Icons](https://github.com/awslabs/aws-icons-for-plantuml)
- **Example**:

  !include 
  !include 
  AMAZONS3(s3_internal,"Default S3")

---

#### **4. Entity Relationship Diagram (Information Engineering Notation)**
- **Extension**: Extends class diagrams with:
- Additional relations (e.g., `|o--`, `||--`, `}o--`, `}|--`).
- Entity aliases and mandatory attributes (marked with `*`).
- **Example**:

  Entity01 }|..|| Entity02
  Entity03 }o..o| Entity04

---

#### **5. Database Diagrams**
- **Features**: Use database elements (e.g., `DEV_MYSQL`) with custom styling.
- **Example**:

  !include 
  DEV_MYSQL(db1, "Database 1", database, white)

---

#### **6. YAML and JSON Data Visualization**
- **YAML**: Activate with `@startyaml` and `@endyaml`.
- **JSON**: Supports JSON data embedding.
- **Example**:

  fruit: Apple
  size: Large
  color: Red

---

#### **7. Known Issues and Workarounds**
- **Word Wrap**: PlantUML does not support automatic line wrapping. Use `\n` for explicit line breaks.
- **Unlinked Elements**: Use `@unlinked` to remove connections.
- **References**: Issues like QA-11052 and QA-13123 are noted.
