Interactive charts
use interactive charts AND use the spreadsheet as a data base (if you change any of the data relevant to this chart in your spreadsheet, the chart will update automatically. You don't need to repeat the steps above to edit this chart).

Organizational Chart
An organizational chart that supports selection.
List all group members in one column of your spreadsheet, and their hierarchical or higher-level relationship in the next column. If you want a tooltip to appear when you point your mouse to each node, you can enter this text in a third column.
