To start the Organization Chart Wizard, click File > New and click the Organization Chart category, and then click Create. If you don’t want to generate a chart automatically, you can draw a chart without using an external data source. If you have all the employee information in a document like an Excel worksheet or in an Exchange Server directory, Visio can generate a diagram that adds the shapes and connectors for you. An organization chart (org chart) is a diagram that shows relationships among employees, titles, and groups.
