The document discusses visualizing geolocated internet measurement data through interactive maps and tools. It notes there is lots of measurement data collected from various network nodes with some geographical data explicitly provided and some inferred. The visualization aims to convey trends in the large amounts of geographical data through dynamic maps that distort maps based on measurements and allow animation of changes over time in an intuitive interface for analysis. Tools discussed include cartograms that distort map sizes based on data amounts and animated maps in an interactive web-based format.

Internet measurements
• Lots of nodes, tons of data
– RIPE services (RIS, TTM)
– Ark monitors @CAIDA
– RIPE Atlas (coming soon!)
• Geographical information
– some obvious/explicit
– some inferred with state-of-the-art techniques

FromData to Visualization
• Why?
– conveyinformation about manydata points
– allow analysis and further development
– observe geographical trends
• How?
– geography as a common knowledge base
– dynamic, interactive, intuitive tools

4. Claudio Squarcella – November 2010 4
Tools: Cartograms
• distortion refects data
• it's still a world map!

5. Claudio Squarcella – November 2010 5
Tools: Animated Maps
• Features
– à la Youtube
– simple interface
– interactive objects
• Under the hood...
– webapp (J avascript)
– vector graphics (SVG)
– server-side computation
