Rents Map - Geohash Example
The example demonstrates server-side geo clustering using relational database (SQL) and geohash index.
The example visualizes on a map apartment rental offers grouping offers located near one another together and representing them using colored circle of variable size. The larger the size, the more offers are available in the area. Color represents a price. Green - low price, yellow - average price, red - high price. When you hover over the circle, detailed information on the number of offers and the price is displayed.
As you zoom in, the clusters are divided into smaller ones. At the maximum zoom level, circles represent individual offers.
