sparks grove's own brian sherwell presents at sxsw - visualizing chronic health
DESCRIPTION
SXSW Interactive Festival's sessions encompass a variety of topics from health, privacy, hacking and design to non-profits, fashion, space exploration and gaming – and everything in between. The common theme at all of these sessions in Austin this year were the values of innovation, creativity and inspiration. This year our own Brian Sherwell presented an innovative approach to understanding chronic health conditions through visualization at one of SXSW's Interactive sessions.TRANSCRIPT

SETTING THE STAGE
WHAT IS DATA VISUALIZATION?Data visualization is the creation and study of the visual representation of data.
or
“just draw it”
WHY VISUAL?
Approximately 70% of the body’s sense receptors reside within the eyes.
It is not just the amount of information collected, but also the subtlety of the information.

The glycemic index is a measure of how quickly blood glucose levels (i.e., blood sugar) rise after eating a particular type of food.
The effects that different foods have on blood glucose levels vary considerably.
