Abstract
In [7] we proposed a visual programming system
called Tioga. The Tioga system applies a boxes and
arrows programming notation to allow nonexpert users to
graphically construct database applications. Users
connect database procedures using a dataflow model.
Browsers are used to visualize the resulting data.
This paper describes extensions to the Tioga browser
protocol. These extensions allow sophisticated, flight
simulator navigation through a multidimensional data
