This chemical reaction mechanism drawing depicts steps of carbonyl compound halogenation reaction.
"Alpha-substitution reactions occur at the position next to the carbonyl group, the α-position, and involve the substitution of an α hydrogen atom by an electrophile, E, through either an enol or enolate ion intermediate. ...
Alpha Halogenation of Aldehydes and Ketones.
A particularly common α-substitution reaction in the laboratory is the halogenation of aldehydes and ketones at their α positions by reaction Cl2, Br2 or I2 in acidic solution. Bromine in acetic acid solvent is often used. ...
The halogenation is a typical α-substitution reaction that proceeds by acid catalyzed formation of an enol intermediate." [Carbonyl Alpha-Substitution Reactions. Wikipedia]

"Package diagrams can use packages containing use cases to illustrate the functionality of a software system.
Package diagrams can use packages that represent the different layers of a software system to illustrate the layered architecture of a software system. The dependencies between these packages can be adorned with labels / stereotypes to indicate the communication mechanism between the layers.
When To Use
- It is used in large scale systems to picture dependencies between major elements in the system
- Package diagrams represent a compile time grouping mechanism." [Package diagram. Wikipedia]

The vector clipart library "Presentation design elements" contains 45 presentation symbols and arrows which you can easy use in your slides and illustrations.
"A presentation is the process of presenting a topic to an audience. It is typically a demonstration, lecture, or speech meant to inform, persuade, or build good will. ... the use of visuals reduced meeting times... audiences believe presenters who use visuals are more professional and credible than presenters who merely speak. ... meetings and presentations reinforced with visuals help participants reach decisions and consensus more quickly."

This concept map example shows concepts and relationship in the geopolitical ontology.
"A geopolitical ontology is a mechanism to describe, manage and exchange data related to geopolitical entities such as countries, territories, regions and other similar areas. ...
An Ontology is a kind of dictionary that describes information in a certain domain using concepts and relationships. It is often implemented using OWL (Web Ontology Language), an XML-based standard language that can be interpreted by computers." [Geopolitical ontology. Wikipedia]

The vector stencils library "IDEF0" contains 26 IDEF0 diagram symbols.
Use it for business process modeling with IDEF0 diagrams.
"The IDEF0 model ... is based on a simple syntax. Each activity is described by a verb-based label placed in a box. Inputs are shown as arrows entering the left side of the activity box while output are shown as exiting arrows on the right side of the box. Controls are displayed as arrows entering the top of the box and mechanisms are displayed as arrows entering from the bottom of the box. Inputs, Controls, Outputs, and Mechanisms are all referred to as concepts.
- Arrow: A directed line, composed of one or more arrow segments, that models an open channel or conduit conveying data or objects from source (no arrowhead) to use (with arrowhead). There are 4 arrow classes: Input Arrow, Output Arrow, Control Arrow, and Mechanism Arrow (includes Call Arrow). See Arrow Segment, Boundary Arrow, Internal Arrow.
- Box: A rectangle, containing a name and number, used to represent a function.
- Context: The immediate environment in which a function (or set of functions on a diagram) operates.
- Decomposition: The partitioning of a modeled function into its component functions.
- Fork: The junction at which an IDEF0 arrow segment (going from source to use) divides into two or more arrow segments. May denote unbundling of meaning.
- Function: An activity, process, or transformation (modeled by an IDEF0 box) identified by a verb or verb phrase that describes what must be accomplished.
- Join: The junction at which an IDEF0 arrow segment (going from source to use) merges with one or more other arrow segments to form a single arrow segment. May denote bundling of arrow segment meanings.
- Node: A box from which child boxes originate; a parent box. See Node Index, Node Tree, Node Number, Node Reference, Diagram Node Number." [IDEF0. Wikipedia]
