Adding More Smartness to Visio Connectors

Whenever I have been asked why I like Visio so much, I have usually cited its ability to connect shapes together; its ability to link to data; and its programmability. Visio 2010 formally added a structured diagram concept and API, and the premium edition introduced diagram validation. So many different types of Visio diagrams require elements to be connected together correctly, and I often have to add a little extra into the connectors to make them smarter.

What is a connector?

A connector is a Visio shape that has 1-D behavior. The most used example is the Dynamic connector shape, which not only connects elements together, but can also re-route itself according to the layout and routing options selected for a page.
