Snap4City dashboard manager: A tool for creating and distributing complex and interactive dashboards with no or low coding

Dashboards are fundamental to inspect data in smart city and industrial contexts. Due to the complexity of such interfaces, dashboard design and construction can be a difficult and time-consuming activity, usually requiring coding competences, not always available among users. In this paper the Snap4City Dashboard Manager is proposed. Unlike other available solutions, the Dashboard Manager allows users to create dashboards in a graphical way by composing widgets able to display multiple kinds of data. Additionally, each widget can be extended to both retrieve data from any source and enable event-driven communications among different widgets and users.
