A displayed map is overlaid with a map-based graphical user interface (GUI). The GUI provides one or more related translucent views corresponding to the displayed map, where each view is associated with a dataset. The GUI also provides interlocked queries and analysis tools to probe the dataset. Each view comprises a polygon layer corresponding to the displayed map and a point layer corresponding to the displayed map, where the polygon layer and the point layer work in tandem to simultaneously display both aggregated and disaggregated data across the displayed map. A selection of a specific item of the point layer or a sub-region of the polygon layer is received from the user. In response, both the point layer and the polygon layer are modified so as to provide additional selectable information corresponding to the received selection and also additional selectable information that may be of interest to the user.
