How to Model a Customized Visualization

Modelling a customized view is a daunting task that takes into account several parameters, the most important being the user profile. In this paper we study many facets of modelisation and the issues that must be taken into account. We propose an approach in four steps to model a personalised visualization: extract data, guess user´s needs and preferences, generate a visualization and finally improve it by user evaluation. It has been applied to the context of weather information in Canada.
