Hi there, Vasanth here - we launched Splittable.co last week (for housesharers) and as part of that, we teamed up with findproperly.co.uk to build and publish a map we thought was interesting for London, showing the location/affordability tradeoffs made for how housesharing can help move you closer to central London. Data is from FindProperly, map visualisation made with some custom JS and google maps. I think Peter from FP is hanging around too so can answer any questions etc. Any comments/feedback welcome!
I put the slider all the way to the maximum - £500 per person per week and there are still some parts of central London that are listed as 'too expensive'. Or perhaps is there no data for those parts?
It is a good idea to use a slider with discretion. Sliders like what you have used is a bad usability practice. I wasn't able to slide the slider at all and I wasn't able to navigate the site at all.
But in cases, where you have limited data points to offer, having the slider bar readjust to the next data point is a good idea.
