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}}.
