OU Related Courses Network Visualisation Using Protovis and Open University Open Data

This is something I’ve been meaning to do for ages, so spurred on by Martin Hawksey’s wonderful Google Gadgets port of my ad hoc Twitter network visulisation thing using Protovis (which Martin points out doesn’t work with IE9), I finally got round to it today: a wiring up of the OU modules Linked Data to … Continue reading “OU Related Courses Network Visualisation Using Protovis and Open University Open Data”

Getting Started With The Gephi Network Visualisation App – My Facebook Network, Part V

A comment from one of the Gephi developers to Getting Started With The Gephi Network Visualisation App – My Facebook Network, Part IV, in which I described how to use the Modularity statistic to partition a network in terms of several different similar subnetwork groupings, suggested that a far better way of visualising the groups … Continue reading “Getting Started With The Gephi Network Visualisation App – My Facebook Network, Part V”

Getting Started With The Gephi Network Visualisation App – My Facebook Network, Part I

A couple of weeks ago, I came across Gephi, a desktop application for visualising networks. And quite by chance, a day or two after I was asked about any tools I knew of that could visualise and help analyse social network activity around an OU course… which I take as a reasonable justification for exploring … Continue reading “Getting Started With The Gephi Network Visualisation App – My Facebook Network, Part I”

Quick Round-Up – Visualising Flows Using Network and Sankey Diagrams in Python and R

Got some data, relating to how students move from one module to another. Rows are student ID, module code, presentation date. The flow is not well-behaved. Students may take multiple modules in one presentation, and modules may be taken in any order (which means there are loops…). My first take on the data was just … Continue reading “Quick Round-Up – Visualising Flows Using Network and Sankey Diagrams in Python and R”

Co-Director Network Data Files in GEXF and JSON from OpenCorporates Data via Scraperwiki and networkx

I’ve been tinkering with OpenCorporates data again, tidying up the co-director scraper described in Corporate Sprawl Sketch Trawls Using OpenCorporates (the new scraper is here: Scraperwiki: opencorporates trawler) and thinking a little about working with the data as a graph/network. What I’ve been focussing on for now are networks that show connections between directors and … Continue reading “Co-Director Network Data Files in GEXF and JSON from OpenCorporates Data via Scraperwiki and networkx”

Therapy Time: Networked Personal Learning and a Reflection on the Urban Peasant…

Way back when I was a postgrad, I used to spend a coffee fuelled morning reading in bed, and then get up to eat a cooked breakfast whilst watching the Urban Peasant, a home kitchen chef with a great attitude: My abiding memory, in part confirmed by several of the asides in the above clip … Continue reading “Therapy Time: Networked Personal Learning and a Reflection on the Urban Peasant…”

Inter-Council Payments and the Google Fusion Tables Network Graph

One of the great things about aggregating local spending data from different councils in the same place – such as on OpenlyLocal – is that you can start to explore structural relations in the way different public bodies of a similar type spend money with each other. On the local spend with corporates scraper on … Continue reading “Inter-Council Payments and the Google Fusion Tables Network Graph”
