Working with a new org chart.
As you saw earlier, you can insert a picture and other graphics by using icons in the Title and Content layout. These include an icon for SmartArt graphics, and these graphics offer org chart layouts as well as all other layouts for diagrams in PowerPoint 2007.
When you click the SmartArt graphic icon:
you get a full gallery of the graphical layouts available.
Org charts and other graphics now have a Text pane in which you can type the text for the chart and work with it outside of the chart's shapes. This is convenient if you prefer not to type directly in the chart.
Also, now you can work in the other direction: Convert an existing bulleted list on a slide into a graphic by using the Convert to SmartArt button on the Home tab.
Look for SmartArt on the Insert tab, in case you prefer to insert a diagram that way.
You can also insert tables and charts from this tab.
