I think some import/export options were deeply buried in Visio 2003. The online help led me to this MS article content:

Create a text or Excel data file to generate a Gantt chart in Visio

1. On the File menu, point to New, point to Project Schedule, and then click Gantt Chart. In the Gantt Chart Options dialog box, click Cancel.
2. On the Gantt Chart menu, click Import.
[...]

There’s also an export option.

For other drawing types, there are similar, buried options, e.g., “Organization Chart” -> Import Organization Data

Hope this helps!
