Provided are a computer program product, system, and method for generating visualizations of facet values for facets defined over a collection of objects. The objects are processed to determine facet values for the objects for a specified facet. A first visualization is generated of representations of the determined facet values for the objects. User selection is received of one of the facet values represented in the generated first visualization. A determination is made of objects having the user selected facet value and a determination is made of at least one facet value for the specified facet for each of the determined objects having the selected facet value. A second visualization of representations of the determined at least one facet value is generated.
