Visualizers Title could be made a link towards the page from where it has been launched.

Stuart:
The Titles for the visualisations seem to reflect where they were launched
from, if this title is active (ie, clicking on it takes me back to where I
came from) then this sort of makes sense, but otherwise I think a title of
the form "<VisualiserName>: <VisualisedDataName>" would make more sense.
LD: I like the idea to make the titles links towards the original place from where the visualizers were launched.
Like that, we can remove the "Back" button (we will most probably do it anyway) from the up-right corner area.
