Example Process Flow Chart

A process flow chart is a sequence diagram on events, actions, tasks and decisions that are visualized in a form of inputs and outputs. Such flow chart involves a defined number of standard symbols and notation keys used to help one understand and pass the information.
Process flow charts have become a day-to-day tool for chemical engineers, technologists and production engineers as well as software developers. However, their use has recently increased in other areas such as business, manufacturing and, especially a service sector.

Data Flow Diagrams

Data Flow Diagrams (DFDs) are graphical representations of the "flow" of data through an information system. Data flow diagrams can be used for the visualization of data processing. ConceptDraw DIAGRAM extended with Data Flow Diagrams Solution is a powerful data flow diagramming application that allows you quickly create any Data Flow Diagrams including the data storages, external entities, functional transforms, data flows, as well as control transforms and signals.

Histogram

Any histogram is known to be an accurate representation of the distribution of numerical data. Being an estimate of the probability distribution of a continuous variable, the histogram was first introduced by Karl Pearson as a kind of a bar graph. To make a histogram, you need to divide the range of values into a series of intervals and then to count how many of the values fall into each of the intervals.
