This chart contains the same information as the chart below, which was created using SmartDraw. Notice how SmartDraw automatically builds the top row horizontally, but the positions reporting to those managers are listed vertically.
Because SmartArt cannot format the lower positions in the chart in columns, it takes up so much horizontal space that the text becomes unreadable. SmartDraw offers much more flexibility and polish than SmartArt. SmartDraw also makes it much easier to move shapes after you have created them. To do this in SmartArt, you must show the text outline and cut and copy the text inside the box to another row.
For anything but the simplest chart, SmartDraw is a much more convenient solution for creating organization charts than trying to develop them with SmartArt tools in Office.
Fortunately, SmartDraw has an easy solution for saving your SmartDraw org chart in Office programs. You can even create a new org chart slide in an existing PowerPoint deck with just a click.
