Ever tried showing pie charts in Magik? Or bar charts or scatter plots? Then tried to label the data points? And create a matching chart legend? Technically, it is all possible in Magik, but the code to manage all that could be quite complex.
Check out this post (http://bit.ly/crW52x) about how Graham at iFactor Consulting has written a Magik interface to the Google Charts API. The possibilities are endless for various kinds of dashboard applications directly in Magik. And I think the charts are also clickable (ie you can drill down on data points). But you might want to ask Graham for more details.
