Getting extra visualizations with NagVis

In this recipe, we'll explore how to go beyond the default network map, discussed in Chapter 8, Managing Network Layout, to get a lot of visualization power with the NagVis extension. NagVis can use the MK Livestatus backend to build custom maps in various styles.
