Abstract
Publishing open government data and providing visualizations that favor the quick understanding and interpretation of the associated information is a task that requires systematization and the use of various technologies. Due to technical limitations (dependence on technological platforms, for example), this is not a standard practice among government system developers. In this work, we present a case study that involves the creation of a map to visualize information about the infestation ofAedes aegypti (dengue vector) in the municipality of Cuiabá, based on the selection and analysis of open data. This case study not only demonstrates that offering an easy way for presenting information on public health brings benefits to the community, but it also discusses a strategy for government agencies publishing open data and creating visualizations that combine information from various sources.
