Visualization of Complex Data – The case study of FUSAMI


With the proliferation of access to the internet, humankind produces and consumes more information than at any other time in its history. The type of data produced ranges from simple pieces of text, to images, video, temporal or geospatial information, among others.

Visualizations try to answer this issue, allowing the understanding and the exploration of large datasets. A good visualization goes beyond the mere static display of information, becoming also the interface with which the user interacts to navigate the data and answering his questions.

The Web Browser has also become the primary window of a user to produce and consume data, being present in every desktop or mobile device with access to the Internet. Mobile Internet usage has surged in the past few years and continues to do so and in the short term will surpass desktop usage. But no longer previously widely used graphic technologies to build visualizations, such as Flash or Java, can be used to produce visualizations that can be viewed in every device, as those technologies are not ubiquitous in mobile devices.

In spite of this unavailability the emergence of HTML5, and other graphic technologies, supported in almost every recent browser, provides an alternative for building visualizations.

The analysis of data can be helpful in many fields, especially analytics and in this thesis we aim to present a case study,

FUSAMI, in the area of analytics of usage of mobile phone applications on how they may be visualized to build better applications, by taking into account the real interaction of the user.
