There are some visualizations (mainly the graphical table and KPI chart) which can already contain limited other visualizations. It would be very useful to introduce the concept of a container in which any type of visualization could be rendered (similar to the containers in TIBCO Jaspersoft). Thus, any table cell would be a container which could contain other visualizations based on the context of that particular cell (/row). This would then enable all types of line charts or bar charts etc to be included in a graphical table, giving Spotfire an unprecedented flexibility.
