Lateral and vertical transformations observed in the study. Lateral transformations can occur through modification of an existing sketch, or through the creation of a new sketch inspired from an existing sketch, to create a new idea. Vertical transformations can occur through adding details such as dimensions,  annotations, or features to an existing sketch, or through a new sketch showing a different detail, to develop an existing idea.

We present a screenshot of the ViSER tool. The supply chain shown is representative of the peripheral computer equipment industry. Each callout points to a specific feature of the ViSER platform and are described as follows: (A) a directed graph that represents the supply chain network as the edges connected to the selected nodes are shown in red, (B) a representation fo the product system graph oriented by a combination of force directed physics and user manipulation, (C) change propagation results for selected nodes of interest, (D) a comparison chart of impact categories for selected nodes of interest, (E) sparklines for each criterion with outliers shown in red and (F) the profile of selected node attributes, e.g.\ time and smog. A video demonstration of ViSER can be found here: \href{http://youtu.be/pDJAqW9H3ME}{\textcolor{blue}{http://youtu.be/pDJAqW9H3ME}}.
