In Pictures: 8 cool heat maps that help visualise Big Data
Big or small, data can be difficult to visualise. These examples use heat maps to put massive data sets into a context that's easy to understand.

While datacentre managers have long used heat maps to help determine where to best position racks of servers and cooling units, this mode of visualisation can also be handy for better understanding system latency, argues an Oracle engineer in the July issue of Communications of the ACM.
