Filters and Search Visualizations Open in the Same View
Previously in DISCO, filters and search visualizations could not be opened in the same view. This release now makes it possible to view filters and search visualizations side by side. With this change, we are making it easier for you to select a filter and view the changes in search visualizations, to better enable you to do your analysis and to identify patterns within your data, without having the need to switch views.
