Abstract:Data visualization is widely considered a key to big data analytics andhas become a hot topic recently. In the 2012 press release of ObamaGovernment's big data initiative, it specially mentioned a US $2 millionfunding support to train undergraduates to use graphical and visualizationtechniques for complex data. At 2013, Tableau Software, a companymarketing interactive data visualization products, raised $254M in IPO andits market value reached almost 4 billion US dollars. Stories about datavisualization and its roles in the big data era are covered in the NewYork Times, Washington Post, Wall Street Journal, Harvard Business Review,Wired, etc.
In this talk, I will first briefly introduce the history of datavisualization, its main research problems and major approaches. I willthen discuss the relationships between data visualization and relatedfields like data mining and human-computer interaction. After that I willtalk about opportunities and challenges for data visualization research inthe big data era. Finally, I will present three ongoing visualizationresearch projects conducted at the Hong Kong University of Science andTechnology: 1) visualization of social media data like Twitter data; 2)visualization of data collected from online education platforms likeCoursera; 3) visualization of trajectory data and air quality data forurban informatics.
