This paper introduces TableView, a tool that helps generate preview tables of massive heterogeneous entity graphs. Given the large number of datasets from many different sources, it is challenging to select entity graphs for a particular need. TableView produces preview tables to offer a compact presentation of important entity types and relationships in an entity graph. Users can quickly browse the preview in a limited space instead of spending precious time or resources to fetch and explore the complete dataset that turns out to be inappropriate for their needs. In this paper we present: 1) a detailed description of TableView's graphical user interface and its various features, 2) a brief description of TableView's preview scoring measures and algorithms, and 3) the demonstration scenarios we intend to present to the audience.
