Social network analysis is the process of identifying people, groups and other entities that are connected to one another in a social structure. It’s widely used in the business world, as it helps businesses determine the most effective ways to market products and services.
There are several free software packages available for social network analysis. These tools make it easy to visualize data and create interactive reports that allow you to explore your data more thoroughly.

- Discovers popular topics or hot discussions
Maps geo-coded social media data
Allows you to conduct social science research on online communities
Overall, the platform can help you find and visualize who is talking to whom within a community, how they are talking about, how often they are communicating, how they actually feel about the topic they are discussing, and the behavior and strength of their interactions with each other.
The best method for: studying large networks with more than 10 million nodes and 100 million edges
A Python library called NetworkX is used to build and examine the dynamics and structure of complicated networks. It is a framework for social network analysis that is relatively scalable, portable, and reasonably effective.

A labeled, directed graph is used by Subdue, a graph-based knowledge discovery system, to describe data. This graph, like all others, has vertices and edges that stand in for various things and relationships.
Subdue can carry out various learning tasks, ranging from clustering and graph grammar learning to supervised and unsupervised learning,
- Discovers repetitive and interesting patterns within a graph
- Finds discriminating patterns from a set of classified graphs

An open-source toolkit called NetworkKit can analyze networks with a thousand to several billion edges.
It makes use of multicore architectures by parallelizing the implementation of various effective graph algorithms. These methods calculate important network metrics like centrality measures, degree sequences, and clustering coefficients.
Some applications function quite well. For instance, community discovery in a 3.3 billion edge web graph on a 16-core server can be completed in under three minutes.
- Includes community detection algorithms
- Describes how networks form and evolve specific structural features.
- Seamlessly integrates with Python libraries for scientific computing and data analysis
That connect two separate modules, NetworkKit provides procedures to convert graph objects to NetworkX. Utilizing the Profiling Module is the most efficient way to acquire a complete view of a network. However, it can make more sense to compute them independently if you are only interested in a tiny fraction.
Most effective for: Managing graph evolution
The dynamics of graphs are the focus of the Java package GraphStream. It provides an easy way to handle and represent complex graphs. Numerous data attributes, including integers, strings, and objects, can be stored in the graph elements.
The graph is defined by GraphStream using “stream of graph events” in addition to nodes and edges. Events are changes to nodes, edges, or any other related components. In this approach, it describes not only a fixed representation but also the full history of how graph elements have changed through time.
Events Found in GraphStream
- Node/Edge addition/removal
- Clear graph
- Graph/node/edge attribute addition or alteration
- Graph/node/edge attribute removal
The library also has features to display graphs beautifully. The viewer displays nodes in an automatic layout, but you can customize the rendering of elements using a CSS stylesheet.
Best for: Representing, modeling, and mapping complex networks

Social Network Visualization
The social network visualization is an excellent way to show the relationships between your friends. You can see who you talk to the most, and who you don’t talk to at all. You can also see if there are any people in your network who might be able to introduce you to new people.
The social network visualization is a great tool for showing how people are connected to each other, and the strength of those connections.
In this example, we can see that people who are more connected are clustered in the center. The more connections they have with others, the more central they are. In this example, there’s a clear divide between two groups: people with more connections (blue dots) and people with fewer connections (orange dots).
This visualization is useful because it helps us understand how people are connected to each other within a system. It also allows us to see how strong those connections are by looking at how many lines connect one person to another.
It’s no secret that social networks have become a huge part of our lives. We use them to stay in touch with friends and family, get news, find new jobs and opportunities, and even just to pass the time. It’s no wonder they’re so popular—they help us connect with others around the world, no matter where we are in life or what we’re doing at any given moment.
But how exactly do all those connections work? How does Facebook know your best friend from high school is getting married? And why does LinkedIn keep sending you emails about job openings that don’t seem quite right for you? What kind of information do these sites have about you, anyway?
We’ve put together this visualization tool to help you see the relationships between different users on various social networks and platforms. The network displays “nodes” representing users and “edges” representing connections between them, allowing you to better visualize who knows who and how often they interact with each other. It can also be helpful if you’re trying to find out more about a particular person or group. For example, if you wanted to know more about your favorite celebrities’ fans, it would be useful to use social network visualizations in order to get an idea of who their most popular fans are and what kind of things they might like doing together.
