dynamic diagrams
the examples directory includes several examples for generating dynamic diagrams from dot markup and stata data sets .
dynamic diagrams helps businesses and organizations transform complex information into clear, engaging communication that drives results. we create :
a dynamic diagrams engagement focuses on communication. our goal isnât an interface facelift or a stock illustration, but a complete audience - centered experience .
the diagrams in this chapter allow you to model the dynamic behavior of your system, how its objects interact at run - time. powerdesigner provides four types of diagrams for modeling your system in this way :
diagram generates dynamic diagrams using dot markup language and exports images in pdf, png, jpeg, gif, and bmp format. for more information visit diagram homepage. it can also generate diagrams automatically from stata data set .

interaction overview diagrams an interaction diagram is a uml diagram that provides a high - level graphical view of the control flow of your system as it is decomposed into sequence and other interaction diagrams .
in addition to the static diagrams, structurizr also supports the creation of a simple dynamic diagram, which can be useful when you want to show how elements in a static model collaborate at runtime to implement a user story, use case, feature, etc .
visual explanations: presentations, videos, animations, illustrations, infographics, and (yes) diagrams .
dynamic diagrams was founded by paul kahn and krzysztof lenk in 1990 as a design studio devoted to presenting information on the computer screen. with the emergence of the world wide web, the company expanded its scope, helping to refine the emergent discipline of information architecture in the process .
the dynamic diagram in structurizr is based upon a uml communication diagram (previously known as a
uml collaboration diagram
). this is similar to a uml sequence diagram although it allows a free - form arrangement of diagram elements with numbered interactions to indicate ordering. as illustrated by the diagrams below, the interactions can be animated .
in the third and final demo segment of our webinar: say goodbye to static documentation, we show you how quick and easy it is to create a dynamic diagram for any problem at hand on - the - fly .

a statechart diagram represents a particular use case or system functionality in terms of the states that a classifier passes through and the transitions between them. for more information, see statechart diagrams .
activity diagrams an activity diagram is a uml diagram that provides a graphical view of a system behavior, and helps you functionally decompose it in order to analyze how it will be implemented .
a sequence diagram represents a particular use case or system functionality in terms of interactions between objects, while focusing on the chronological order of the messages sent. for more information, see sequence diagrams .
communication diagrams a communication diagram is a uml diagram that provides a graphical view of the interactions between objects for a use case scenario, the execution of an operation, or an interaction between classes, with an emphasis on the system structure .
a activity diagram represents a particular use case or system functionality in terms of the actions or activities performed and the transitions triggered by the completion of these actions. it also allows you to represent conditional branches. for more information, see activity diagrams .
sequence diagrams a sequence diagram is a uml diagram that provides a graphical view of the chronology of the exchange of messages between objects and actors for a use case, the execution of an operation, or an interaction between classes, with an emphasis on their chronology .
statechart diagrams a statechart diagram is a uml diagram that provides a graphical view of a state machine, the public behavior of a classifier (component or class), in the form of the changes over time of the state of the classifier and of the events that permit the transition from one state to another .
interaction references and interaction activities (oom) an interaction reference is used to represent one sequence diagram in the body of another. this feature allows you to modularize and reuse commonly - used interactions across a range of sequence diagrams. interaction activities are similar, but are able to represent a sequence, communication, or interaction overview diagram .
a major problem that learners face in comprehending animated diagrams is in decomposing the presented information into a form that furnishes appropriate raw material for building high quality mental models. this paper proposes an alternative to existing design approaches that shifts the prime focus from the nature of the external representation to the internal composition activity learners engage in during mental model construction .
user experiences: we can help you make a website, design user interfaces, intranets, and interactive applications .
even with two decades of experience, we know that information design is not going to change the world. but we can make it easier to understand .
now under the direction of tim roy, the company continues to expand its horizons, providing solutions not only in the area of user experience design of web sites and applications, but also visual explanation .
we begin with an deep analysis of your business goals, content, and audience. we explore the links between these elements and develop a strategy for bringing your idea, product, or web site to life. we review that strategy with you and your stakeholders. then we apply powerful visual tools to distinguish your information â in a presentation designed to reach your audience .
we call this process âdesign for understandingâ and it can help your organization produce lasting business benefits .

messages (oom) a message is a communication between objects. the receipt of a message will normally have an outcome .
activations (oom) activations are optional symbols that represent the time required for an action to be performed. they are created on the lifeline of an object. they are purely symbols and do not have property sheets .
interaction fragments (oom) an interaction fragment allows you to group related messages in a sequence diagram. various predefined fragment types are available allowing you to specify alternate outcomes, parallel messages, or looping .
activities (oom) an activity is the invocation of a manual or automated action, such as
send a mail
, or
increment a counter
. when the activity gains control, it performs its action and then, depending on the result of the action, the transition (control flow) is passed to another activity .
organization units (oom) an organization unit can represent a company, a system, a service, an organization, a user or a role, which is responsible for an activity. in uml, an organization unit is called a swimlane, while in the oom ,
swimlane
refers to the symbol of the organization unit .
starts (oom) a start is a starting point of the flow represented in the diagram .
ends (oom) an end is a termination point of the flow represented in the diagram .
decisions (oom) a decision specifies which path to take, when several paths are possible .
synchronizations (oom) a synchronization enables the splitting or synchronization of control between two or more concurrent actions .
flows (oom) a flow is a route the control flow takes between objects. the routing of the control flow is made using guard conditions defined on flows. if the condition is true, the control is passed to the next object .
object nodes (oom) an object node is the association of an object (instance of a class) and a state. it represents an object in a particular state .
states (oom) a state represents a situation during the life of a classifier that is usually specified by conditions. it can also be defined as the situation of a classifier waiting for events. stability and duration are two characteristics of a state .
transitions (oom) a transition is an oriented link between states, which indicates that an element in one state can enter another state when an event occurs (and, optionally, if a guard condition is satisfied). the expression commonly used in this case is that a transition is fired .
events (oom) an event is the occurrence of something observable. the occurrence is assumed to be instantaneous and should not have duration .
actions (oom) an action is a specification of a computable statement. it occurs in a specific situation and may comprise predefined events (entry, do and exit) and internal transitions .
junction points (oom) a junction point can merge and / or split several input and output transitions. it is similar to the decision in the activity diagram

the diagram package relies on webimage package for exporting the graphs to various formats. for more information regarding the latter package, visit webimage on github. both packages are installable via github .
the diagram package requires webimage _ _ stata package for exporting the graphical files. the github package can be used to install diagram and its dependency, webimage, as shown below :
moreover, for exporting graphical files, the webimage package requires phantomjs, which is an open - source freeware available for windows, mac, and linux. the path to the executable phantomjs file is required in order to export the graphical files. however, if the executable file is installed in the default local directory (e. g. / usr / local / bin / on mac or c: \ phantomjs \ bin \ phantomjs. exe on windows), the phantomjs (str) can be ignored .
in the examples directory, there is a dot file named path1. txt which draws a path diagram. the file is rendered by diagram command and exported to a png file directly from stata :
