Visualizer is the tool that helps the user when creating policies in Hapi. It is responsive, intuitive, and provides the user from any device with access to the WEB a simple and always-ready graphical interface.

This tool aggregates all the functionalities available in the Hapi project so far, namely: Translator, Matrix Printer and Lattices Print.

In addition, the application also has Error Notification, which appears in cases where the program is written outside the syntax defined for the Hapi Language. The error message indicates the line and the probable cause of the error presented, thus facilitating the user's correction through the Visualizer itself.

This tool is freely available online through the link: Visualizer. More information on its practical usage will be given in sequence.
