The Cloud shows the distribution of police incidents across the county. Similar to a weather radar map, the areas of highest intensity are those with the most activity. If enough incidents are shown on the map, you start to get a pretty good idea of where the "hot spots" are.
Here's how it works. Each time you click the button below, you add 500 points to your cloud. Each point is a police incident of some kind. The more points you add, the better your cloud looks. However, the Cloud is likely to make your computer work very hard. It will take a few seconds to load each set of points. During this time, your browser may become unresponsive. This will intensify with each set of points, and your browser, or even your computer, may eventually stop functioning entirely. I generally stop at about 4000 points, but this will vary depending on your computer's RAM and CPU.
I promise that it's entirely worth it. But you ought to finish anything important you happen to be doing before you try this. To sum up:
