Catalogue Visu: a Tool for Fast Visualization Prototyping

Visualization is an essential tool for exploring, understanding and presenting data. However, its use is limited by knowledge and tools. Novice users in visualization do not always know which visualization to choose for their data. The realization of a visualization with specific tools is often long and complex. In this article we present Catalogue Visu, an application allowing the free and fast realization of visualizations. Our main contribution is the design of the choice of the visualization type, which allows any user to choose an appropriate visualization for his needs. This method, the heart of Catalogue Visu, is iteratively validated by three user studies. Catalog Visu is accessible online and in permanent evolution, and is already used internally as a prototyping tool.
