Advanced Gephi filters

Advanced Graph Visualization with Gephi Video:

In the previous sections, we used COVID-19 dataset for graph visualization that contain no edges. In this section to show more advanced capabilities of Gephi software, we'll use Mapping Letters over Europe dataset from Martin Grandjean.

Due to the fact that this graph has edges besides nodes, we need to load to separate files that take care of nodes and edges respectively.

In Gephi software, similar to previous sections load Nodes1.csv for nodes:

In order to load edges, choose Edges1.csv file and set the Import as configuration to Edges table:

Force atlas 2 layout configuration:

  • Force Atlas 2 layout configuration is one of the most useful layouts that could be used to rearrange the graph based on graph degree.

  • Scaling parameter would tune the distance between nodes after rearrangement.

The arranged graph after applying Force Atlas 2 is shown below:

Edges appearance configuration:

  • Similar to nodes appearances, the same procedure could be used to change the color of edges based on attributes:

High quality rendering of graph with edges:

  • The high quality rendering of graph with edges is shown here:

Statistical analysis of the graph:

  • There are statistical analysis tool in Gephi to analyze the clusters such as finding the average degree in the graph, network diameter, modularity, etc.
