I'll be presenting a session at TechEd in Boston on programming the new Visio 2007 data features. Here are the session details:

Microsoft Office Visio 2007: Building Data Visualization Solutions
Day/Time: Thursday, June 15 8:00 AM - 9:15 AM  Room: 259 AB
Speaker(s): Bill Morein
Your application deals with huge amounts of data, and making sense of that information and communicating it broadly is vital to making your users successful. Learn how to incorporate dynamic views of data into your smart client application using the new data visualization capabilities in Microsoft Office Visio 2007. Stepping through the creation of an example application, topics covered include connecting to data sources (e.g. Excel, Access, SQL Server, SharePoint lists, and XML), programmatically mapping that data to shapes, and surfacing the data on the diagram using the Data Graphics API.
