Setting the primitives

•Vertices – nodes in a graph (People)•Edges – connection between vertices

(Relationship)•Groups – cluster of vertices•Graph type (directed or undirected)•Graph Layouts and Graph Refresh

Show or refresh graph

Setting / Viewing edges, vertices, groups

Selecting a vertex to view the associated graph

Exploring the basic functionalities with a simple graph

Setting Graph type and layout

Grouping Vertices and Setting visual indicators

Measuring and Visualizing networks

•Calculating Graph metrics [Degree (in & out) , Betweenness, Closeness centrality and many others]

•Generate sub graph of the graph•Auto fill columns [ Setting filters and

visualization options for edges, vertices and groups like opacity (relationship determinant), labels (for naming), visibility threshold etc]

Graph metrics calculation &sub graph generation options

Auto fill options ( mainly visual properties and determinants)

Sample dataset (Kite_Net) graph

Sample dataset (Senate_voting) graph

Data set Import options

Visualize your facebook network

•Download your social network data with the app - https://apps.facebook.com/namegenweb/

•Choose to download in the GraphML format•Save it to your local machine and make sure

that the extension of the file is “.graphml”•Now import your graphml file in NodeXL and

play with it (Identify your friend clusters, calculate the graph metrics, add filters…)

Closing thought !

Network data is now available - it’s organization’s turn to use social network analysis results to formulate its organizational, marketing and branding strategies in its Next gen Knowledge (harvesting & rendering) Platforms.
