  1. 9. Software for network visualisation and analysis • Criteria • Free • User friendly manual • On-screen network drawing is easy • Imports and exports multiple formats • Ability to display attributes by colour/size/shape • Continuing to be developed • Multiple layout options • Multiple network measures Who has used what software? Hands up exercise

  2. NodeXL, an Excel Template • Free, manual exists, continuing development • You can give nodes and links as many different attributes as desired • Including objective descriptions, results data • And these can be visualised in the colour/size/shape of nodes and links

  3. yED, diagramming software • Free • Wide range of ways of visualising differences in nodes and links • Copes with Excel files that vary in their layout • Diagrams can be uploaded as interactive web pages

  4. UCINET & NetDraw • The most widely used SNA package • Lots of data manipulation and network analysis tools • Lots of layout and filtering options • Continually being developed • Steep learning curve • Courses available

  5. Visualyzer • Very easy on screen drawing • User friendly manual • Attributes of nodes and links can be made visible by mouse-over, clicks and coding • Expensive • Not under continuing development

  6. The attributes of the actors can be made visible by cursor rollover+shift

  7. 10. Participants’ plans for possible post-workshop applications • Participants (in 3’s) brainstorm a possible network mapping exercise, with each identifying: • What sort of project ? • At what stage ? • Using what sort of data ? • Involving who ? • To document a plan or a current reality ? • At what level of detail ? 30

  8. 11. Workshop Evaluation • One page feedback form • Post-workshop requests for help • 1 hour for each person, by skype and or email • Follow up participants’ survey • On possible post-workshop connections between participants 30

  9. Qualitative feedback.. • Like and should keep • Don’t like, but should improve and keep • Don’t like and should remove • Missing and should be added
