When looking around for network visualization software, it's more important to seek the functionality required to manage large networks, rather than just looking at the (artificial) node limits. Although it is very easy to implement a Graph ADT in Python, we will use networkx library for Graph Analysis as it has inbuilt support for visualizing graphs. The only problem is that if your application is too big or there are many graphs plottes on the same figure then it lags if you try to move the graph around or try to zoom in. Let's go ahead and import the dataset directly from networkx and also set up the spring layout positioning for the graph visuals:. Any feedback is highly welcome.
