Doing data visualization well on the mobile form factor is a challenge. Making a highly interactive data visualization that is also a web based application can be downright daunting.
The challenge in creating data visualization for such small form factors is that the typical design and interactive affordances used in a desktop application don’t work. On the desktop, users have a mouse, which can have pin-point accuracy. On a mobile device, users have a finger which can not be as accurate in selecting pixels. Desktops generally have much more screen real-estate to show data, mobile does not. So the challenge is how to present the same volume of data to users while allowing them to navigate that data, all on a smaller form factor.
The web application you see below is a step in that direction. You can view it live here.
