6. LIVE Singapore!
Provides people with access to a range of useful real-
time information about their city by developing an
open platform for the collection, elaboration and
distribution of real-time data that reflect urban
activity. Giving people visual and tangible access to
real-time information about their city enables them to
take their decisions more in sync with their
environment, with what is actually happening around
them.

23. Three Visualization Modes
• Map View
• Time-Series View
• Arcs View
Switching between these lets users focus on one view,
and still enables them to select the best fitting one in
order to gain insights based on different data
properties.
