(was: Sorry for pending this ticket for a long time. I've re considered how and what to visualize.
One of my ideas,  "Timeline based visualization" for each task at a stage,  is taking a shape and almost be implemented.

This feature is integrated into existing WebUI, zoomable and scrollable.
Now the code of this feature is a little bit messy but I'll cleanup and show the code soon.)

> I sometimes trouble-shoot and analyse the cause of long time spending job.
> At the time, I find the stages which spends long time or fails, then I find the tasks which spends long time or fails, next I analyse the proportion of each phase in a task.
> Another case, I find executors which spends long time for running a task and analyse the details of a task.
> In such situation, I think it's helpful to visualize timeline view of stages / tasks / executors and visualize details of proportion of activity for each task.
> Now I'm developing prototypes like captures I attached.
> I'll integrate these viewer into WebUI.
