Systems and methods for extending a visualization platform are disclosed. A user may create a visualization project created. One or more properties for a non-native widget established by a developer of the non-native widget may be received from the project. Such properties may designate a name or a type of data that the non-native widget is capable of processing. Responsive to an instruction received from the user of the visualization authoring environment, a source of data to be processed by the non-native widget or a destination of data produced by the non-native widget to be processed by other widgets may be established. The appearance or behavior of the non-native widget may be rendered based at least in part on a value available from the source of the data or the appearance or behavior of one or more other widgets may be rendered based at least in part on data produced by the non-native widget.

A direct digital drive audio system and method system and method are presented. The direct digital drive system and method utilizes a digital signal to directly drive the speakers. In one exemplary implementation, an audio system includes a sample register, an convergence adjustment component, an accumulated error register, a digital driver and a speaker. The sample register is coupled to the convergence adjustment component which is coupled to the accumulated error register and the digital driver which in turn is coupled to the speaker. The sample register holds an audio sample. The convergence adjustment component calculates the error for each sample. The accumulated error register stores an accumulated error. The digital driver determines whether to drive on a positive digital value, drive on a negative digital value or not drive. The speaker creates audio sounds based upon a signal from the digital driver.
