Stevie May June 24, 2019 Flowcharts
Flowchart Designer is a great app for mac to try first. You can choose from basic, equation, rectangle, and flowchart objects. Just pick one and then drag and drop it onto the canvas. Insert duplicate objects by double-clicking a blue arrow and to add a connector, just drag the blue circle to another object. You can pop in text easily for all shapes and include labels for connectors.
Algorithms and flowcharts are two different ways of presenting the process of solving a problem. Algorithms consist of a set of steps for solving a particular problem, while in flowcharts, those steps are usually displayed in shapes and process boxes with arrows. So flowcharts can be used for presenting algorithms.
The diamond symbolizes that a decision needs to be made. If there are only two choices, you can draw arrows directly from the diamond to the next step (example on the left). If there are more than two choices, you can draw them neatly by copying the example on the right.
