Visio shapes range from very simple to very detailed.
What is a shape? In Visio, the definition is much broader than you might think. Yes, you can use basic shapes like rectangles and diamonds for a flowchart. But you can also use very detailed shapes.
For example, shapes can represent streets and buildings in a map. They can symbolize computer equipment in a network diagram. There are even furniture shapes for office floor plans. Sound like a lot? There are hundreds more.
And Visio shapes don't just sit there and look good. They have interactive behavior as well. Meaning, when you work with them, they react in a certain way.
