Edraw Max contains some symbols for designers to draw the relationship
diagrams. For example, the Counterbalance Arrows layout in the Relationship type is designed to represent only two opposing ideas or concepts, and so only two of the shapes can contain text.
Find the symbols in the List, Process, Charts and Graphics library.
Equation Diagram

Use to show sequential steps or tasks that depict a plan or result. The last
Level 1 line of text appears after the equals sign (=).Works best with Level
1 text only.
Arrow Ribbon
Use to show either related or contrasting concepts with some connection,
such as opposing forces. The first two lines of Level 1 text are used for
text in the arrows. Unused text does not appear, but remains available if
you switch layouts.
Balance Diagram

Use to compare or show the relationship between two ideas. Each of the first
two lines of Level 1 text corresponds to text at the top of one side of the
center point. Emphasizes Level 2 text, which is limited to four shapes on
each side of the center point. The balance tips towards the side with the
most shapes containing Level 2 text. Unused text does not appear, but
remains available if you switch layouts.
Basic Radial Diagram
Use to show the relationship to a central idea in a cycle. The first line of
Level 1 text corresponds to the central shape, and its Level 2 text
corresponds to the surrounding circular shapes. Unused text does not appear,
but remains available if you switch layouts.
Basic Target Diagram
Use to show containment, gradations, or hierarchical relationships. The
first five lines of Level 1 text are associated with a circle. Unused text
does not appear, but remains available if you switch layouts.
Basic Pie Diagram

Use to show how individual parts form a whole. The first seven lines of
Level 1 text correspond to the evenly distributed wedge or pie shapes. The
top Level 1 text shape appears outside of the rest of the pie for emphasis.
Unused text does not appear, but remains available if you switch layouts.
Basic Venn Diagram
Use to show overlapping or interconnected relationships. The first seven
lines of Level 1 text correspond with a circle. If there are four or fewer
lines of Level 1 text, the text is inside the circles. If there are more
than four lines of Level 1 text, the text is outside of the circles. Unused
text does not appear, but remains available if you switch layouts.
Counterbalance Arrows
Use to show two opposing ideas or concepts. Each of the first two lines of
Level 1 text corresponds to an arrow and works well with Level 2 text.
Unused text does not appear, but remains available if you switch layouts.
Cycle Matrix
Use to show the relationship to a central idea in a cyclical progression.
Each of the first four lines of Level 1 text corresponds to a wedge or pie
shape, and Level 2 text appears in a rectangular shape to the side of the
wedge or pie shape. Unused text does not appear, but remains available if
you switch layouts.
Diverging Arrows
Use to show ideas or concepts that progress outward from a central source.
Works best with Level 1 text only.
Diverging Radial
Use to show relationships to a central idea in a cycle. The first Level 1
line of text corresponds to the central circular shape. Emphasizes the
surrounding circles rather than the central idea. Unused text does not
appear, but remains available if you switch layouts.
Funnel Diagram
Use to show the filtering of information or how parts merge into a whole.
Emphasizes the final outcome. Can contain up to four lines of Level 1 text;
the last of these four Level 1 text lines appears below the funnel and the
other lines correspond to a circular shape. Unused text does not appear, but
remains available if you switch layouts.
Gear Diagram

Use to show interlocking ideas. Each of the first three lines of Level 1
text corresponds to a gear shape, and their corresponding Level 2 text
appears in rectangles next to the gear shape. Unused text does not appear,
but remains available if you switch layouts.
Nested Target Diagram
Use to show containment relationships. Each of the first three lines of
Level 1 text correspond to the upper left text in the shapes, and Level 2
text corresponds to the smaller shapes. Works best with minimal Level 2
lines of text. Unused text does not appear, but remains available if you
switch layouts.
Nondirectional Cycle
Use to represent a continuing sequence of stages, tasks, or events in a
circular flow. Each shape has the same level of importance. Works well when
direction does not need to be indicated.
Radial Cycle
Use to show the relationship to a central idea. Emphasizes both information
in the center circle and how information in the outer ring of circles
contributes to the central idea. The first Level 1 line of text corresponds
to the central circle, and its Level 2 text corresponds to the outer ring of
circles. Unused text does not appear, but remains available if you switch
layouts.
Radial Venn Diagram

Use to show both overlapping relationships and the relationship to a central
idea in a cycle. The first line of Level 1 text corresponds to the central
shape and the lines of Level 2 text correspond to the surrounding circular
shapes. Unused text does not appear, but remains available if you switch
layouts.
Segmented Pyramid
Use to show containment, proportional, or interconnected relationships. The
first nine lines of Level 1 text appear in the triangular shapes. Unused
text does not appear, but remains available if you switch layouts. Works
best with Level 1 text only.
Table Hierarchy Diagram
Use to show groups of information built from top to bottom, and the
hierarchies within each group. This layout does not contain connecting
lines.
Vertical Equation
Use to show sequential steps or tasks that depict a plan or result. The last
Level 1 line of text appears after the arrow. Works best with Level 1 text
only.
