Zoopla Property Price Maps

I've just come across yet another interesting heatmap as I was browsing property websites, as you do...
This time the heatmap is from Zoopla, the property search website, and shows the different prices of property in different parts of the country, with the highest priced areas being shown in red and the lowest areas in blue. 
The heatmap is a collaboration with Google Maps and also shows the average property price for each area. View it properly HERE.
Here are some snapshots...

I zoomed in to look more closely at London property prices, which not surprisingly showed up as the most expensive area in the UK.

If you click on each price sticker it gives you a more precise number for the average property price, as well as telling you the name of the area.

Heatmap of Tripadvisor's Most Visited Restaurants

Unfortunately Google Fusion doesn't let you publish heatmaps for geocoded addresses, so instead I've taken screenshots of the effect, which you can see below.
The redder the heatspot, the more people have visited the place and left reviews on Tripadvisor.

It's cool how the further you zoom out, the more the heatspots blur into one...
