摘要：Nowadays, based on the amount of available data, there are situations in which the information visualization becomes fundamental for the understanding and interpretation of the data. In this context, the study aims to relate and explore, through visualization techniques, open educational data in a multidisciplinary context. For that, a Web application was developed for data visualization of the Brazilian national high school exam (ENEM). In this study, the ENEM microdata was obtained from the Brazilian open data portal. As a result of the comparative analyzes performed on the data, by states, regions and types of schools, it was observed which states obtained the highest and lowest averages of ENEM in relation to national averages. For example, in the state of Santa Catarina, students from private schools obtained 12.70% above the national average for that type of school and the lowest average age of enrolled students corresponding to 21.6 years old. The visualization Web application made possible a comparative analysis on the large dataset and the exploration of visual representations that would be difficult to perform through traditional approaches.
