Some graphic tools let you create these diagrams or flowgrams, but it is much better to use a free utility like BizAgi Process Modeler which is specifically designed for this task.
With BizAgi Process Modeler you can create a diagram and document business processes (flowgrams) easily, intuitively and speedily. It is based on the standard BPMN notation.
