A computer-implemented method of visualizing a dataset is implemented on a computer having memory, one or more processors, and a display. The method includes: rendering multiple objects on the display in a tiled manner, wherein each object is a visualization of a respective set of fields of the dataset and there is no overlap between the objects; in response to detecting a first user instruction, switching the rendition of at least one of the objects from the tiled manner to a floating manner; in response to detecting a second user instruction, moving a first object to a location on top of a second object, wherein the location is determined by the second user instruction such that at least a portion of the second object is covered by the first object; and in response to detecting a third user instruction, updating both the first object and the second object.
