An extended reality (XR) software application program executing on a processor within an XR system generates drill-down data visualizations in an XR environment. Via the XR software application program, various techniques are performed for displaying panels that include visualizations of data. In a first technique, the XR software application program generates, in response to detecting a user interaction with a portion of a first panel, a drill-down panel that includes additional visualization(s) of data associated with the portion of the first panel and is displayed in front of the first panel within the XR environment. In a second technique, the XR software application program generates and displays multiple drill-down panels that include visualization(s) of the selected data and are displayed in a tree structure within the XR environment.
