Adi,

I believe this election data has been around for years. The demarcation 
board lists all the ward data, it used to be that one had to ask for it 
specially.

Great work, Fantastic stuff.

Some comments - I don't believe that your 10% criteria is a fair 
reflection of the "safety" of that ward. I believe that a better method 
would be to colour code the winning party, and write its victory total 
(ie 55% of all votes) and its margin of victory in percentage (by ward) 
- ie if the winning party got 55% and the next party got 35%, then it 
won by 20 points.

When a party wins by the 65% upwards range, then it could be considered 
safe. Of course their may be better ways, but with a title aimed at 2016 
I do think it should reflect percentage victories to portray to people 
the possibilities in that data - how safe it is, perhaps with a merger 
it could change, if people of one party dont vote because of a viable 
alternative - who would win etc... - a whole miriad of possibilities.

Regards

Peter
