Nowadays several cities have been involved in research in order to encourage the creation of solutions that provide the data and information to the population, are the so-called City Dashboards. These projects enable citizens to follow the events of the city in real time, enabling these people to plan their routines based on the knowledge generated about their local context. Currently, many solutions of this genre have been developed around the world, however, a very large range has its technology-centered design. That is, the focus is on implementation and reaching an end product. This can lead to inconsistency in interface patterns, making usability more difficult, and ultimately rejecting those projects on the part of users. Therefore, this work aims to create a framework from Bootstrap customization, implementing web interface standards focused on common contents for intelligent cities, using Node-RED as the execution platform. It is hoped to contribute to the reduction of the tooling needed to build more effective interfaces for information visualization in city dashboards, as well as in improving the productivity of software development and maintenance teams.
