Wind roses typically use 16 cardinal directions, such as north (N), NNE, NE, etc., although they may be subdivided into as many as 32 directions. A wind rose plot may contain additional information, in that each spoke is broken down into colour-coded bands that show wind speed ranges.

Each concentric circle represents a different frequency, emanating from zero at the center to increasing frequencies at the outer circles. The length of each 'spoke' around the circle is related to the frequency that the wind blows from a particular direction per unit time. Presented in a circular format, the modern wind rose shows the frequency of winds blowing from particular directions over a specified period. North was depicted with a fleur de lis, while east was shown as a Christian cross to indicate the direction of Jerusalem from Europe. No differentiation was made between cardinal directions and the winds which blew from those directions.

When drawing generalization or realization hierarchies on a diagram always make sure the parent elements are higher than the child elements so the arrows always point upwards.Before the development of the compass rose, a wind rose was included on maps in order to let the reader know which directions the 8 major winds (and sometimes 8 half-winds and 16 quarter-winds) blew within the plan view.

When drawing connectors, having lines with multiple connectors make diagrams look messy and confusing.

Try to make sure all lines go horizontally or vertically and create right angles with each other.

If two lines must cross, use a “bridge” to show that the lines do not intersect. This allows your diagrams to be more readable and understandable.

Avoid lines crossing over each other while creating UML diagrams.

When creating UML diagrams you can create multiple diagrams of different workspaces and link them together for better comprehension. Creating unnecessarily complex diagrams with too much information can confuse stakeholders.

When creating UML diagrams it is important to remember to create levels of abstractions that meet the need of your audience.

Things to Remember While Creating UML diagrams UML diagrams visually represent a system along with its main actors, roles, actions, artifacts or classes, in order to better understand, alter, maintain, or document information about the system.

UML or Unified Modeling Language is a modeling technique used to document software.
