1. A method comprising:

  • receiving, by a system including a processor, topics identified from records based on scoring candidate terms in the records according to a user-specified metric received by the system, and at least one further metric selected from among frequencies of occurrence of records pertaining to the candidate terms, and negativity of sentiment expressed with respect to the candidate terms in the records;

    determining if each of the candidate terms corresponds to a critical event based on event detection data associated with each of the candidate terms;

    generating for display, by the system, a visualization including bubbles representing the topics using the candidate terms that correspond to the critical event, wherein the bubbles each include pixels representing corresponding records, and further wherein a given bubble of the bubbles has a shape dependent upon a number of records represented by the given bubble and a time interval represented by the given bubble;

    assigning, by the system, visual indicators to the pixels in the given bubble according to values of an attribute expressed in the corresponding records for a topic of the topics represented by the given bubble;

    updating the visualization to create a new time interval if a newly received record is outside a current time interval; and

    visualizing the newly received record in the new time interval.
