Travel management company Travel and Transport has launched its Big Data subsidiary, Data Visualization Intelligence, and plans to begin selling its first data aggregation tool by the end of this year. Announced last year, the tool, DVI Vantage Point, will provide corporate travel programs with graphics detailing traveler activity and spending, pulling data not only from expense reports, travel management companies and corporate cards but also from outside the travel sphere. Travel and Transport is working with select clients on the tool.
