There is one more place that I think adding graphs would be beneficial. It
is query profiling information. Simple bar graph would easily show what
stage of query execution takes the most time.

I was also wondering about charts themselves. In ideas list, it was
mentioned that graphs would be drawn using GD2.

Another way is to use Google Chart Tools. These tools offer two different
types of charts.

First one is simple image charts, which are retrieved using GET or POST
queries from Google servers. Another type is Javascript/Flash charts which
offer interactivity but take longer to load.

Since charts would be offered in specific non-mission-critical places of
PMA, loading any type of mentioned two from outside servers should not be a
problem. Also there should be a logic introduced to switch between chart
types by the current browser capabilities.
