This report discusses the design and implementation of a subsystem required for the Illuminator, which is an energy system integration demonstrator. The purpose of the subsystem discussed in this report is visualising incoming simulated power flows, visualising the output data of various emission and finance data and also change various input parameters. This system has been realised using Dash, which is the python framework used for building the dashboard web application. A study case is provided to better understand the use of the demonstrator.
