Visualization of Economic Input-Output Data

In this paper, visual techniques used to present economic input-output data are described. These techniques were created because the size of the data matrices and the screen limitations complicate data navigation. These techniques allow users to ask questions about detailed and global information. The techniques were designed based on the user tasks. The graphic techniques are combined with direct manipulation techniques to improve the ease and efficiency with which users interact with the system. The software prototype uses I992 US economic data.
