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
