    Hi all,
    Here’s a visualization from Marc Smith (@marc_smith), which uses the post-conference week data: https://twitter.com/marc_smith/status/396303552596803584
    Once you click the link for his social network map, try clicking on “view an interactive version of this graph.” I like that version because it helps you see the strength of the relationships between players.
    Enjoy! Ann

  3. Hi Johanna, I always have troubles showing the labels – I sometimes manage and sometimes I don’t – do you know the trick?

    Hello Joitske, let’s see, for the version of NodeXL I’m using, the steps are:
    1. Working in the “Vertices” tab of the spreadsheet: In column C (“Visual Properties” section, column “Shape”), change the value for all cells to “Label”. You can do this by selecting all of the cells and clicking on the NodeXL tab, then on “Vertex Shape” and then on “Label.”
    2. In column H (“Labels” section, column “Label”), change the value for all cells to reflect the lable you want displayed—often a copy-paste from the name of the vertex itself.
    3. On the map, click “Show Graph” or “Lay Out Again.” Your map should now have labels. It might be messy, but they’re there! Now make it pretty:)
    Hopefully that works for you, too!

How to Make a Social Network Map with NodeXL

Basic social network analysis is something EVERYONE can do. So let’s try out one social network analysis tool, NodeXL, and take a peek at the Twitter hashtag #eval13.

Using NodeXL (a free Excel plug-in) I will demonstrate step-by-step how to do a basic social network analysis (SNA).

What is Social Network Analysis?

SNA is a dataviz approach for data collection, analysis, and reporting. Networks are made up of nodes (often people or organizations) and edges (the relationships or exchanges between nodes).

The set of nodes and edges that make up a network form the dataset for SNA.

Like other types of data, there are quantitative metrics about networks, for example, the overall size and density of the network.

How to Create a Social Network Map in NodeXL

There are four basic steps to creating a social network map in NodeXL:

  1. Get NodeXL.
  2. Open NodeXL.
  3. Import data.
  4. Visualize the data.

    Why Social Network Analysis is Valuable

    Here’s where SNA gets fun—there is a lot of value in visually analyzing the network.

    Yes, your brain can provide incredible insight to the analysis process. In my evaluation consulting experience, the partners I have worked with have consistently benefited more from the exploratory, visual analysis they have benefited from reviewing the quantitative metrics. Sure, it is important to know things like how many people are in the network, how dense the relationships are, and other key stats.

    But for real-world applications, it is often more important to examine how pivotal players relate to each other relative to the overall goals they are trying to achieve.

    Your Turn

    So here’s your challenge—what do you learn from analyzing the #eval13 social network data?

    Share your visualizations and your findings!
