What is a flowchart?
The Merriam-Webster dictionary defines flowchart as “a diagram that shows step-by-step progression through a procedure or system especially using connecting lines and a set of conventional symbols.”
What does this mean and why should I care? Good question. What it means is that a flowchart can be used to break big ideas into small, bite-sized pieces that are expressed visually. You should care because knowing how to flowchart is like having access to a Universal language which makes it possible to communicate all sorts of things with all sorts of people, and that’s pretty cool.
Basic flowchart symbols
First things first, in order to create a good flowchart you must first familiarize yourself with the most commonly used flowchart symbols.
1. The Oval
An End or a Beginning
The oval is used to represent the start and end of a process. Use the Gliffy flowchart tool to drag and drop one of these bad boys and you’ve got yourself the beginnings of a flowchart. Use the same symbol again to show that your flowchart is complete.
2. The Rectangle
A Step in the Flowcharting Process
The rectangle is your go-to symbol. It represents any step in the process you’re depicting and is the workhorse of the flowchart diagram. Give it a lump of sugar and it will love you forever.
3. The Arrow
The arrow is used to guide the viewer along their flowcharting path. And while there are many different types of arrow tips to choose from, we recommend sticking with one for your entire flowchart. It’s less confusing and generally more aesthetically pleasing.
4. The Diamond
Call for a Decision
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.
