“Visual.ly” claims to be “The world’s largest community for exploring, sharing, creating, and promoting data visualizations.”
Currently, there are over 3000 visualisations available on their site. Among my current favourites is this Infographics on Communication Through The Ages by Atlassian and this topological map of the internet, also available for download as desktop-wallpaper or poster here (at peer1hosting).
Well, data visualisation requires first of all that we get the appropriate data put together. With this all-important and often painful task pandas offers some help, pandas is “… becoming the most powerful and flexible open source data analysis / manipulation tool available in any language.” – they say. Sounds good, it’s based on numPy (scientific computing package for Python), will have to try it out at some point.
