Create A Weighted Graph From a Pandas Dataframe. The first task in any python program is importing necessary modules/libraries into the code. The next task is to create a data frame for which the graph needs to be plotted in the later sections. The same can be obtained with the help of the pandas and numpy module.

Basic Network from pandas data frame. This example is probably the most basic network chart you can draw. A network chart is constituted by nodes. These nodes are interconnected by edges. So a basic format is a data frame where each line describes a connection. Here we construct a data frame with 4 lines, describing the 4 connections of this plot!

The dataframe shows when different investment firms have invested in the same Company during a year. I want to create a network graph of the Connections between the Firm_ID only. For example Ampersand and BancBoston have both invested in the same company and should therefore be connected. To make the network manageable, we only consider the strong connections by keeping edges with weights>10. This trims down the graph to 80 nodes (characters) and 175 edges (connections). Loading this data, which is in pandas dataframe format, as a network is quite easy. It can be done using NetworkX as follows,
