Social Network Features
One of the differentiators for NodeXL from other point-and-click graph
software is its specific functionality for the analysis of social networks. It
provides tools that make it easy to acquire social network data, load it into
Excel, extract social network-specific data such as top hashtags, and follow
links back to web sources.
Social Network Data Acquisition
Compared to manually collecting data and creating a graph as described
in Chapter 3, NodeXL makes social data acquisition much easier (although
it may not collect a large amount of historical data). To facilitate data
acquisition from a social network, NodeXL provides wizards to walk you
through the process.
