UK election facts clarified with interactive graphics

I’ve been impressed with this website (constituencyexplorer.org.uk) put together by Jim Ridgway and colleagues at Durham, with input from the House of Commons Library and dataviz guru Alan Smith from the ONS. In part, it is aimed at members of parliament, so they can test their knowledge of facts about constituencies and learn more along the way. But it makes for a fun quiz for residents too. Everything is realised in D3, so it runs everywhere, even on your phone. There are a few features I really like: the clean design, the link between map, list and dotplot in the election results:

constituency-explorer-results

… the animation after choosing a value with the slider, highlighting the extra/shortfall icons and the numbers dropping in: nice!

constituency-explorer-quiz

… the simple but quite ambitious help pop-up:

constituency-explorer-prolegomena

… and the way that the dotplots are always reset to the full width of the variable, so you can’t be misled by small differences appearing bigger than they are. The user has to choose to zoom after seeing the full picture.

All in all, a very nice piece of work. I must declare that I did contribute a few design suggestions in its latter stages of development but I really take no credit for its overall style and functionality. Budding D3 scripters could learn a lot from the source code.

And while we’re on the topic, here some more innovative electoral dataviz:

And finally, take a moment to ask election candidates to commit to one afternoon of free statistical training, a great initiative from the RSS – and frankly, not much to ask. Unfortunately, none of my local (Croydon Central) would-be lawmakers have been bothered to write back yet. But here’s the parties that are most interested in accurate statistics, in descending order (by mashing up this and this):

  1. National Health Alliance: 4/13
  2. Pirate Party: 1/6
  3. Green Party: 47/568
  4. Labour Party: 51/647
  5. Plaid Cymru: 3/40
  6. Liberal Democrats: 47/647
  7. Ulster Unionist Party: 1/15
  8. Christian People’s Alliance: 1/17
  9. Conservative and Unionist Party: 27/647
  10. Scottish National Party: 2/59
  11. United Kingdom Independence Party: 15/624
