The discussion will take into account a special case of construction of “FlashGraph” in a yahoo based widget format that uses the XML data generated by the sensor devices installed for monitoring domestic electricity consumption. Flash is chosen as programming language since it can be used for quickly assembling web applications and creating widget. We overcome the difficulties of Flash to access external devices and process the data generated by introducing a very generic concept: The XML information generated by input devices is transferred to a PC where a program collects them, interprets them and makes them available on a web server. The flash widget component can now access the data that is stored in XML format and directly use it in the application. July - September 2009 Copyright © 2009 i-manager publications.
