  The increasingly rapid growth of data production and the consequent need to
explore data to obtain answers to the most varied questions have promoted the
development of tools to facilitate the manipulation and construction of data
visualizations. However, building useful data visualizations is not a trivial
task: it may involve a large number of subtle decisions that require experience
from their designer. In this paper, we present VisMaker, a visualization
recommender tool that uses a set of rules to present visualization
recommendations organized and described through questions, in order to
facilitate the understanding of the recommendations and assisting the visual
exploration process. We carried out two studies comparing our tool with Voyager
2 and analyzed some aspects of the use of tools. We collected feedback from
participants to identify the advantages and disadvantages of our recommendation
approach. As a result, we gathered comments to help improve the development of
tools in this domain.
