In particular, our approach aims to solve the problems practitioners encounter in their daily work life when they have to consult different text-based documents to get access to the same data we provide in a single interface. To test the suitability of our system, we conducted a formative study where participants used our system to answer both simple and complex questions previously designed in collaboration with a domain expert. Our results indicate that our target users can easily work with our system and use it to answer both types of questions.Attribution 4.0 International LicenseCCS Concepts: Human-centered computing -> Visualization systems and tools; Empirical studies in visualization; Visual analyticsHuman centered computingVisualization systems and toolsEmpirical studies in visualizationVisual analytics10.2312/evp.2023106965-673 pages
