1. A system comprising: a result acquisition component that obtains a plurality of incremental query results and a plurality of confidence interval values associated with respective ones of the incremental query results; a visualization object determination component that determines, via a device processor, a plurality of visualization shape objects indicating uncertainty values, based on mapping values of respective ones of the incremental query results and confidence interval values to points in the associated ones of the visualization shape objects, the uncertainty values visualized based on proportional shapes of the visualization shape objects; a visualization comparison component that determines at least one visualization comparison object representing a comparison of a plurality of distributions associated with the obtained incremental query results and confidence interval values; and a visualization object output component that initiates display of the plurality of visualization shape objects and the at least one visualization comparison object.
