Interactive Visualization of Multiple Data Sources Across Multiple Computers

A data pool receives first data derived from user-generated input that identifies events that have occurred at the corresponding remote first computing system. Thereafter, the data pool generates messages based on the identified events that specify data to be extracted from each of a plurality of data sources. The data pool then transmits data comprising the generated messages to at least one of a plurality of data daemons. The data pool subsequently receives second data extracted and processed by the data daemons in response to the transmitted data. In addition, the data pool transmits at least a portion of the received second data to at least one remote second computing system to enable the remote second computing system to render visualizations that are based on the received data and which are displayed within at least one data lens that overlays a substrate in the graphical user interface.
