Everybody loves a good map projection, none more so that the nerds here at UCL’s CASA.
I made a little toy visualisation of survey responses per global region for a pal of mine at Kings College, but knew he’d be unhappy with my choice of projection. So I decided to take the decision out of my hands and give control to the user.
The result is this fun little way of playing with map projections, relishing the smooth animations from one projection to the next. Go on, pick your favourite!
Data-driven economics 
Talking of good map projections, I am reminded each time I demonstrate our percolation work on defining hierarchies of clusters at different distance thresholds for Europe, I use a projection which I refer to as the Powerpoint projection. Asked to change the aspect ratio on my PPT slides a few months ago, i did so to elongate the slides and of course the map of Europe adjusted accordingly. As yet my version of PPT doesn’t have a facility to keep the dimensions as you set them up – thus my version of Europe now is no longer Mercator but Elongated Mercator, which is a class of projections I call ‘Powerpoint’ Nerdy enough for you, Rob?
