    UML 2.5 shape library with updated shapes

    The Unified Modeling Language (UML) is a set of standard symbols and diagram types, commonly used in data modelling, workflow visualisation, and system modelling. UML notation is the defacto industry standard in the fields of software development, IT infrastructure, business systems and other fields. Many languages, such as SysML, SoaML, and a number of architecture frameworks use and extend UML.

    Automatic layout shapes for flow charts, tree diagrams and mind maps

    The automatic layout shapes in the Advanced shape library in diagrams.net organise your flow charts, tree diagrams, org charts, and mind maps for you as you add and connect more shapes. The automated layout ensures that all shapes in your diagram are spaced evenly, either in a horizontal or vertical format, and will automatically increase or decrease the container shape’s size to match the contents.

    Create diagrams directly in VS Code

    Diagrams make coding go a lot smoother, especially when you are programming in teams. Having diagrams version tracked and right with the code they reference, and version tracked similarly in your code editor saves you time. You don’t have to exit your workspace to switch to an external tool, or have to export/import every time you want to update a diagram.

We like to categorise everything as it helps us make sense of how the world works. Species of plants and animals, corporate and military hierarchies, team structures, family trees, language family relationships, even symptoms of illnesses - org charts help us quickly find who to contact, what illness to treat, and so on.
