Marks:
[Rectangles] mark encodes [the amount of money].
Visual channels:
[position-y] channel encodes [the rank of the amount of money].
[color] channel encodes [the amount of money (the darker, the larger the amount)].
Who is the audience?
The audiences for this visualization are people who read articles from Bloomberg, NYtimes, The Guardian, Washington Post, or World Bank. They may be interested in numbers behind the business world and market value behind companies like Apple. Also, the audiences may also be people who are passionate about social issues like income disparities and resource disparity between the 99% of people in the world and the top 1%.
Message and questions behind this visualization:
The primary goal of this visualization is to give comprehensible meanings to big numbers, like 1 trillion. For example, it uses Apple’s market value to represent 1 trillion and 13 trillion to represent the US’s household debt. It uses the size of the squares to compare the different aspects, for example, the world GDP has a much bigger square than Apple’s market value, proportional to their actual sizes 1 trillion vs. 75.6 trillion. The secondary goal of this visualization is to emphasize the wealth discrepancies between the 99% of people in the world and the top 1%. As shown in the graph, the wealth of the top 1% is on the lower right corner, which means the top 1% has more money than the money in all the world’s central banks, the world GDP, and even the total global debt. This visualization emphasizes the huge problem of income inequality in the world and raises awareness for this issue.
What data is encoded in the visualization?
Information on market value, GDP, debt, and wealth, and their corresponding values in trillions.
How does the visualization encode the data?
The visualization encodes the data in the Trillion Dollar-o-Gram, which utilizes the sizes of squares to compare the values.
What tasks do readers perform on the visualization?
Readers are able to compare values, gain an understanding of the relations between different aspects, and also identify the extreme (wealth of top 1%).
How are the five principles applied to this visualization?
Truthful: The visualization is truthful since it showed the data in context using the sizes of the squares and disclosed the data source.
Functional: The visualization was very easy to read, used accurate sizes of squares to represent numbers, and it supports the meaningful task: to provide context for large numbers.
Beautiful: The font and color progression adopts minimalist design principles and is very easy to read. Also, it is free of unnecessary elements.
Insightful: The visualization helped to confirm my belief in the wealth discrepancy in our society, but it revealed to me that the discrepancy is much larger than I thought.
Enlightening: The visualization went beyond the numbers and insights. It raised awareness of socio-economic issues that exist in our society.
Why is this visualization good?
As we talked about in class, context is very important when we want to represent data. This visualization provides the context for readers to understand what 1 trillion really means and how it compares to other important concepts like world GDP and wealth of the top 1%.
It also raised awareness for the income and wealth gap between the 99% and top 1%.
