Tips to Build Javascript Activity Diagrams with DHTMLXĭhtmlxDiagram library consists of plenty of diagram types like flowhcarts, org charts, decision trees, and UML activity diagrams among them. In order to make a diagram more descriptive, textual notes are often provided near shapes and arrows. Nodes are linked with arrows showing the flow of activities. Arrows flow out of decision shapes and are directed to separate rectangles to create several scenarios for further activities.īesides, these diagrams may include other flowchart shapes – for example, to illustrate the connection with another diagram. It occurs when an activity results in several outcomes, which lead to different steps to be taken next. Rectangles reflect activities themselves – what needs to be done.ĭecision shapes serve as crossroads, a point where there’re two or more possible ways to follow. The circle shape marks the start and end points of activity diagrams. These diagrams may also include iterations when an error or other unfavorable event occurs, and an arrow is being directed to one of the previous activities to be repeated.Īctivity diagrams are usually built using 3 types of shapes: For example, the first activity diagram we had a look at above describes the necessity to prepare both a room and laptop for meeting a client that is shown by parallel arrows leading to two different rectangular shapes. UML activity diagrams are distinguished by the possibility to illustrate parallel activities. It concerns both simple operations and more complicated functions. Developers apply this diagram type to formulate how a system or program should behave. However, UML activity diagrams may be applied even on a larger scale describing any workflow, which shows all possible occurrences in the course of events.Īnother field of use of activity diagrams is programming. This diagram type is widely spread in business analysis for illustrating particular business use cases and activities involved in them. This means that they are used for showing how something behaves under certain circumstances taking into account different scenarios. For that reason they’re often defined as behavioral diagrams.
