Diagram as Code - Use AI to generate UML Diagrams
People & Blogs
Introduction
In the world of software engineering and architecture, visualization plays a vital role in communicating designs and architectures. Traditionally, drawing diagrams has been done through graphical software like draw.io or Microsoft Visio. While these tools are functional, they have certain drawbacks that make standardization and collaboration challenging.
Challenges of Traditional Diagramming Tools
One significant issue with using graphical tools is the variance in notation and symbols between different architects or engineers. For instance, while one engineer might adhere to standard UML diagrams such as class diagrams, another may simply use a generic box to represent a class. Additionally, color coding and labeling systems can differ from one professional to another, complicating collaborative efforts and hindering the ability to standardize designs across teams.
Another downside to graphical diagramming tools is the difficulty in storing and versioning designs in a source control system. Such tools typically output image files or proprietary formats that are not easily managed in version control.
Diagramming with Code
An alternative approach to traditional diagramming is using a declarative language or code. Among the various systems available, PlantUML stands out as a popular choice, capable of generating standard UML diagrams, such as sequence diagrams and class diagrams, as well as other visualizations like UI mockups and Gantt charts.
Another noteworthy system is Mermaid, which has gained prominence for its ease of use, including integration with Visual Studio Code. By utilizing the live editor feature in Visual Studio Code, users can quickly create and modify diagrams. Moreover, Mermaid provides sample diagrams, which can be especially beneficial for those who are just learning its markup language.
Utilizing AI for Diagram Generation
AI tools, such as ChatGPT, can significantly enhance the diagramming process. By providing a description of the scenario to generate UML diagrams, users can save time and effort. For example, if a developer describes a situation involving a Vehicle class with a property called Wheels and a Car class that inherits from Vehicle with an additional property called Color, the AI can generate the corresponding Mermaid markup code.
This code can then be copied into an editor where it can be further refined and adjusted to meet the project's specific needs. Additionally, the generated code can be stored in repository hosting services like GitHub or GitLab, allowing for easy modification and version control.
Conclusion
In summary, adopting a code-based approach to diagramming not only enhances consistency and standardization across teams but also leverages the power of AI to simplify the creation process. This combination of tools ultimately strengthens clarity and communication within software projects.
