UML is a simple and effective tool that helps to create visual representations of workflows using flowcharts and diagrams. It can be used by anyone. It does not require any development skills to use this. However, if you know coding, then it's an advantage. As a Business Analyst, this tool helps me a lot to create flowcharts, user stories, use case diagrams, etc. It has really helped me in my professional career. I will recommend this tool to people who are looking for tools that help in creating visual diagrams.

yUML allows its users who are not designers a way to create diagrams with text commands.
