Draw anything you want. To draw perfect shapes like a circle, hold the Shift button while drawing.
Click Save and Close. If you don't want to save the changes, click the X button on the top right corner.
Adding new shapes from the Excalidraw Libraries website
To add new shapes, visit the website and click the Download button to save the collection you need to your computer. The downloaded library file's extension is .excalidrawlib.
Do not use the Add to Excalidraw button, as the library will not be added to the plugin-hosted Excalidraw Editor.
Open the Excalidraw Editor in Confluence, and upload the library file.
You can then drag and drop shapes into the canvas.
Adding shapes to library
To add a shape to library, select the shape, right-click on it, and click Add to Library.
To save your shapes library locally (e.g. for backup purposes), select the shape in the library panel, and click Save to in the menu.
Mermaid UML Diagrams Macro
In the Confluence editor, insert the Mermaid UML macro.
A dialog will appear. Type the content of the UML diagram into the macro editor. Here is an example:
sequenceDiagram
participant Alice
participant Bob
Alice->>John: Hello John, how are you?
loop Healthcheck
John->>John: Fight against hypochondria
end
Note right of John: Rational thoughts <br/>prevail!
John-->>Alice: Great!
John->>Bob: How about you?
Bob-->>John: Jolly good!
PlantUML Diagrams Macro
In the Confluence editor, insert the PlantUML macro.
Type the content of the UML diagram into the macro editor.
In the Confluence editor, insert the Graphviz macro.
Type the content of the Graphviz diagram into the macro editor. Here is an example:
graph {
a -- b;
b -- c;
a -- c;
d -- c;
e -- c;
e -- a;
}

The PlantUML macro () uses PlantUML to render UML diagrams. It allows you to define UML diagrams in plain-text format just like Markdown.

Some PlantUML diagrams requires Graphviz to be installed in the Confluence server . If you cannot install Graphviz, try adding !pragma layout smetana to the diagram content to enable the Smetana engine .
You can find more examples here . The PDF guideline can be downloaded here .
The Graphviz layout programs () take descriptions of graphs in a simple text language, and make diagrams in useful formats, such as images and SVG for web pages; PDF or Postscript for inclusion in other documents; or display in an interactive graph browser. Graphviz has many useful features for concrete diagrams, such as options for colors, fonts, tabular node layouts, line styles, hyperlinks, and custom shapes.
