I love how easy it was for me as an individual user/data professional with little experience in analytics or visualization tools (but willing)to create custom dashboards by combining existing datasets into one dashboard - even if they were not compatible! The ability also allows you flexibility when creating new ones through open APIs which gives more control over your own creations.
There are still some issues regarding API limits but this has since been resolved so everything should be fine now? Maybe try out other free products first before purchasing something like tellium would give better results than my previous statement about limitations may suggest :) Some things can get confusing at times such us connecting different datasources together etc.. However all these problems did manage solve very easily once we understood them properly!! This tool will really help any small teams who need access quick insight without having too much knowledge within IT / Data Science departments especially those looking forward towards becoming "big" companies later down road where budgets allow bigger investments made elsewhere.
