Flowcharts are diagrams that illustrate processes using different symbols. They are used to visually illustrate a sequence of instructions for a task or process. Originally developed for mechanical engineering in 1924, they have since become an integral part of a variety of computer science tasks such as programming, software development, and data analysis.
Flowcharts can be used to define, visualize, document, or analyze a process, showing it in a much simpler and more straightforward way than with a written description. They are composed of carefully arranged shapes, symbols, and arrows to represent the flow of instructions through the system or software program. Flowcharts can be used to outline algorithms, determine a process, and show decision points, as well as details such as variable declarations and loops.
Flowcharts are frequently used to improve communication, efficiency, and navigation to solve complex problems. They make complex tasks easier to grasp by providing clear descriptions of the steps required and showing potential interactions between different elements.
Flowcharts are composed of different shapes that represent the elements and steps of the process. These elements can be used to represent functions, operations, decisions, inputs, or outputs. The most common symbols are those used in the popular flowcharting tools Visio or Lucidchart. They include rectangles, squares, diamonds, circles, arrows, and others. More complex diagrams may also include icons, text bubbles and hyperlinks.
Flowcharts are commonly used in business, engineering, and software development, but are useful for any process that requires visualization and understanding. Well designed flowcharts are clear, easy to read, and include all necessary steps.
