How to Add Annotations to Nodes and Connectors in Angular Diagram

Learn how to add annotations to nodes and connectors in the Angular Diagram component. The Angular Diagram is a feature-rich diagram library for visualizing, creating, and editing interactive diagrams. It supports creating flowcharts, organizational charts, mind maps, and BPMN charts either through code or a visual interface.

An annotation is a block of text that can be displayed over a node or connector. Annotations are used to represent an object textually with a string that can be edited at runtime. Multiple annotations can be added to a node or connector.

You will learn how to customize annotations using properties like horizontal alignment, vertical alignment, offset, and margin. Additionally, I will show you how to modify the appearance of annotations using text wrapping and font styles. The offset property of an annotation is used to align the annotations based on fractions. 0 represents the top-left corner, 1 represents the bottom-right corner, and 0.5 represents half of width or height. We’ll set the size for an annotation using width and height properties.

The horizontalAlignment property of annotations is used to set how the annotation is horizontally aligned at the annotation position determined from the fraction values. The verticalAlignment property is used to set how an annotation is vertically aligned. When text overflows node boundaries, you can use text wrapping to wrap it into multiple lines.
