Data Visualization – Visualizing Relocation Factors

Is it worth to relocate?

A 11-week graduate project from research to design & development using Tableau. See final paper here and all design artifacts here.

Problem

Deciding whether it's worth to relocate is difficult. This solution that takes in multiple government data sources and synthesizes data into digestible data visualization that helps people to compare city facts.

 

Design Question

How can we help people visualize reliable data and make a better decision?

 

Process

Research Question > Research data, cleaning & analysis > Design & Usability Test > Iterate

 

Research

Datasets covering 11 metropolitan areas  from multiple government sources were imported and mined.

Dataviz - Research

7 user interviews & surveys were analyzed to understand existing experience and factors affecting their decisions.

 

Design

Mindmap, personas, & Balsamiq prototype. View all design artifacts here.

Dataviz - Design 1

Earlier concept (image on right above) shows the use of tabs to display in-depth information for each factors, but this model makes comparison between the factors difficult.

 

Test

Usability tests revealed common errors in data encoding/labelling, and content navigation challenges. New opportunities were identified (e.g. "Crime rate and weather should be helpful." ~participant).
