Graph improvements

[emilw]

Really nice tool!

Improvements that would be nice are:

• Be able to see the resource without hoovering over them when using Anotate group. Its hard to share the plan now without needing to explain what the colors mean
• See an end date of the project, in the graphs there is no end date visible.
• Looking at the metrics summarization you can see total duration in month, but no end date
