“…While fully automated analysis yields tremendous benefits such as speed, scientific objectivity and reproducibility [31], full automation also has a number of issues: i) it ignores the analyst's knowledge that cannot be formalized [57]; ii) it yields only minimal exposure to the data and therefore does not encourage deep understanding [22]; iii) it may produce errors that can be way more costly than the effects of human subjectivity [58]; and iv) it often produces visualizations that are suboptimal for communication. For example, cluster analysis throw out lots of data and can produce results that are controversial, subject to misinterpretation, or meaningless [32,39,51].…”

This is the accepted version of the paper.This version of the publication may differ from the final published version. Abstract-We present BERTIFIER, a web app for rapidly creating tabular visualizations from spreadsheets. BERTIFIER draws from Jacques Bertin's matrix analysis method, whose goal was to "simplify without destroying" by encoding cell values visually and grouping similar rows and columns. Although there were several attempts to bring this method to computers, no implementation exists today that is both exhaustive and accessible to a large audience. BERTIFIER remains faithful to Bertin's method while leveraging the power of today's interactive computers. Tables are formatted and manipulated through crossets, a new interaction technique for rapidly applying operations on rows and columns. We also introduce visual reordering, a semi-interactive reordering approach that lets users apply and tune automatic reordering algorithms in a WYSIWYG manner. Sessions with eight users from different backgrounds suggest that BERTIFIER has the potential to bring Bertin's method to a wider audience of both technical and non-technical users, and empower them with data analysis and communication tools that were so far only accessible to a handful of specialists.

“…He concluded that automatic reordering can save time but needs to be interlaced with manual tweaking. Semi-automatic approaches to matrix reordering have been argued for since then [33,51]. Devising semi-automatic methods however requires a good understanding of automatic methods.…”

“…In the latter, structural and temporal patterns could be exhibited on correlation matrices. Although the orderability of matrices can enhance user performance with regards to certain tasks [8], finding the appropriate order on a correlation matrix is a task-dependent question that will be receiving increasing interest [18,10].…”

Large financial institutions such as Bank of America handle hundreds of thousands of wire transactions per day. Although most transactions are legitimate, these institutions have legal and financial obligations in discovering those that are suspicious. With the methods of fraudulent activities ever changing, searching on predefined patterns is often insufficient in detecting previously undiscovered methods. In this paper, we present a set of coordinated visualizations based on identifying specific keywords within the wire transactions. The different views used in our system depict relationships among keywords and accounts over time. Furthermore, we introduce a search-by-example technique which extracts accounts that show similar transaction patterns. In collaboration with the Anti-Money Laundering division at Bank of America, we demonstrate that using our tool, investigators are able to detect accounts and transactions that exhibit suspicious behaviors.

“…The algorithm also minimizes the summed length of all links, ensuring that the vertical layout is as packed as possible. To order individuals and families within each layer, we minimize link crossings using the "barycenter heuristic" published by Siirtola & Mäkinen [35]. dot implements a slightly improved version.…”
