Finding Meaningful Relationships in Data
OBJECTIVE
Allow data to show us relationships that are worth highlighting and understanding what kind of data we must have, to help answers the questions we ask.
APPROACH
By understanding the data and relationships inward, we can communicate it outward.
Visualization is about finding the right fit between the dataset and the story
DETAILS
This project was a part of the Grad Communication Design Studio at the CMU School of Design (5 weeks)
#1
Identify An Area of Research
The context of looking for researchable questions based on data was within Allegheny County and/or the City of Pittsburgh. Crime was interesting to me because of one maybe able to correlate crime rates with many environmental factors like temperature and accessibility and also infrastructural issues like street lighting. I was interested in how crimes are categorized, Within those I was interested in how the movement and activity of criminals was affected by the weather and seasons.
I STARTED WITH THIS QUESTION
What do people try to find out about a city when they are planning to move there?
Is it affordable?
How is the weather like?
How accessible is transport?
How low are crime rates?
I have been interested in the factors that drive crime in a city. My approach in this project was to look at seemingly unrelated aspects of a city and find relationships between them. The relationship between crime and temparature was an interesting starting point

Collecting Data Sources
To start answering some of the questions framed above, I started looking at sources of data about crime rates in Pittsburgh and Allegheny County. The data sources known and reliable institutions and organisations.
Framing Researchable Questions
Framing a question that elicited an answer beyond yes know was a way to find multiple relationships and use the data sets to find those patterns. The question I started with, after looking at articles and data available was -
How does seasonal change affect the nature of crimes and offences committed or reported in Pittsburgh/Allegheny County?
