Generate a complete graph with annotations:

Retrieve the annotation value associated with an annotation name:

Change the annotation value:

Unset the annotation value:

Get intrinsic MeshCellMeasure annotations for cells in a mesh:

Automatically compute annotations for an Audio object:

Retrieve annotations for louder intervals:

Use Do to set several annotation values:

Or different annotation values for different items:

Use Table to build a list of annotation values:

Create a weighted graph:

Set edge weights:

Compute weight scale:

Set the edge thickness to reflect the edge weight:

Highlight a path and mark the start point and endpoint:

Select vertices along a path:

Highlight by setting edge style along the path and vertex labels for start point and endpoint:

Dynamically highlight the edges in the order given by EdgeList:

Do five updates a second:

Dynamically visualize breadth-first search:

Use Annotation as a wrapper to specify annotations in functions such as Graph:

AnnotationValue returns $Failed for undefined annotations:

Use AnnotationKeys to test for the presence of an annotation:

Generate a list of vertex label rules:

Use Annotate to set an annotation without changing the original:

The original graph is unchanged:

Use AnnotationDelete to remove an annotation without changing the original:

The original graph is unchanged:

AnnotationValue returns $Failed for undefined annotations:

Use AnnotationKeys to test for the presence of an annotation:

AnnotationValue may return $Failed even when an annotation value exists:

Use AnnotationKeys to check for actual annotation values:
