The ability to visualize many different datasets in one dashboard has been helpful when trying to identify patterns that are not directly apparent from raw numbers. I have noticed some minor lag time between clicks, which causes slight delays in visual updates. However this is easily rectified by refreshing (or reloading) the page or opening another tab with your results so you don't lose any existing charts/data points. We're using our dashboards as an internal reporting system but can be used externally too if needed - we've already had several requests made about external use of course! This software allowed us to rapidly produce very clear graphs within minutes instead of hours previously required.
