# VertexLabels

 VertexLabels is an option and property for Graph and related functions that specifies what labels and label positions should be used for vertices.
• The following option settings can be used:
 None use no vertex labels Automatic automatically label vertices "Name" use the vertex name as a label {v1->lbl1,v2->lbl2,...} label vertex with etc.
• The wrapper Labeled is equivalent to Property and can be used when creating graphs in functions such as Graph etc.
• Any expression can be used as a label.
• Labeled and Placed can be used to place labels in relative position to the vertex box.
• The following positions pos can be used for Labeled and Placed in positioning vertex labels:
 Tooltip, StatusArea show as tooltip or in status area on mouseover Center place label at center of vertex Before,After,Below,Above place label outside before, after, etc. Left,Right,Bottom,Top place label inside to the left, right, etc. {Before,Below},{After,Below},... place label outside at corner before/below, etc. {Left,Bottom},{Right,Bottom},... place label inside at corner left/bottom, etc. {{vx,vy},{lx,ly}} scaled position in the label at scaled position in the vertex
Label individual vertices:
Label all vertices:
Use any expression as a label:
Label individual vertices:
 Out[1]=

Label all vertices:
 Out[1]=

Use any expression as a label:
 Out[1]=
 Scope   (15)
Use vertex names as labels:
VertexLabels can be used for general graphs:
Matrix graphs:
Special graphs:
Random graphs:
Use VertexLabels in a Property wrapper:
Alternatively, use a Labeled wrapper:
Use Placed with symbolic locations to control label placement, including outside positions:
Symbolic outside corner positions:
Symbolic inside positions:
Symbolic inside corner positions:
Use explicit coordinates to place the center of labels:
Place all labels at the upper-right corner of the vertex and vary the coordinates within the label:
Place multiple labels using Placed in a wrapper:
Any number of labels can be used:
Place multiple labels using VertexLabels:
Use the third argument to Placed to control formatting including Tooltip:
Use more elaborate formatting functions:
