Exploring the Spectrum of Diagrams:
What Varieties Await?

Class Diagram


Diagram illustrates the structure of a system by showing the classes of the system, their attributes, methods, and relationships between them

  • Depicts the static structure of a system
  • Shows the relationships and dependencies among classes
  • Can be used for both high-level system design and detailed modeling of software components

Database Diagram


Diagram provides a visual representation of a database schema, including tables, columns, relationships, and constraints

  • Displays the logical and/or physical structure of a database
  • Illustrates the relationships between different tables/entities
  • Can include constraints such as primary keys, foreign keys, and indexes

Entity-Relationship Diagram


Diagram depicts entities, their attributes, and the relationships between them, commonly used in database design to model real-world objects

  • Focuses on the entities and their attributes
  • Shows the relationships and associations between entities
  • Often used in database design or business process modeling

Graph Diagram


Diagram visualizes relationships between nodes (vertices) and edges (connections), commonly used in network analysis, social network analysis, and data visualization

  • Represents network-like structures
  • Can be directed or undirected
  • Commonly used in social network analysis, network routing, and data visualization

Mindmap Diagram


Visual representation of hierarchical information, organizing ideas or concepts around a central theme, often used for brainstorming, note-taking, and planning

  • Organizes information in a non-linear manner
  • Facilitates brainstorming, note-taking, and organizing thoughts
  • Typically starts with a central idea and branches out into related topics or subtopics

Pie-Chart Diagram


Circular statistical graphic divided into slices to illustrate numerical proportions, commonly used to show percentages or proportions of a whole

  • Represents proportions or percentages of a whole
  • Useful for comparing parts of a whole
  • Easily interpretable for showcasing data distribution

Sequence Diagram


Diagram shows how objects interact in a particular sequence, illustrating the messages exchanged between objects over time

  • Shows the chronological order of messages exchanged between objects
  • Useful for visualizing the dynamic behavior of a system
  • Typically used in system design, especially for modeling scenarios and interactions

Timeline Diagram


Provides a chronological order of events or milestones, often used to visualize historical data, project schedules, or process timelines

  • Displays events or activities in sequential order
  • Can include durations, start/end dates, and dependencies between events
  • Useful for illustrating historical events, project schedules, or process timelines
