My professional life is mostly related to business analysis, reporting, operation, and people management, which is not design again. Lucky enough, when working with GreenTown China, my previous company, I had extensive involvement in business and data analysis and reporting. Even more lucky, I was working with a group of excellent designers and had been involved in many reviewing meetings about their works, interior design review for interior decoration projects, graphic design review for company advertising projects, heard the designers talking about line, color, form, pattern, focal point, etc, I gradually used to apply these design principles into my work when it comes to reporting and found those principles also fit data visualization.
