#46 Various stylistic improvements

Questions

How many topics would you like to show on the left side ?
The map doesn't want to resize. The svg width/height changes but the map does not resize
The barchart for the languages, even if it resizes, the bar width does not change (rowChart bar size changes automagically)
I'm doing an extra redraw/render for each graph so that it occupies the space of their container, to avoid any initial overlap
Didnt use renderlet, I did it ~like in your blog post
Changed the text color of the rowChart to something dark. I didnt use a light text color as you suggested, cause we would have the same issue, light color text on white background
Im getting uncaught exception: Mandatory attribute chart.dimension is missing on chart[#topics-chart] even if everything works fine
