The current load indicator (the small spinner in the upper left of reports) isn't really sufficient for users. On our larger reports, which can take a while to load, the user sees a large empty area ...
At a minimum I would want the spinning dots to be positioned centered in the middle of the visual, and also featured more prominently so that they are more easily seen. Ie increase the size of the whole spinning graphics thing. Also, if the visual for some reason is dark, the color of the spinning dots need to be inversed so that they are seen and dont just blur into the dark background.
