How 5 Tech Giants Make Their Billions

How 5 Tech Giants Make Their Billions is a good doughnut-style data visualization design from Visual Capitalist.

These five tech companies are the most valuable stocks in the U.S. market, worth a collective $2.9 trillion in market capitalization. In 2016, these companies combine for $555 billion in revenue, and a $94 billion bottom line.

Each of these companies is pretty unique in how they generate revenue, though there is some overlap:

• Facebook and Alphabet each make the vast majority of their revenues from advertising (97% and 88%, respectively)
• Apple makes 63% of their revenue from the iPhone, and another 21% coming from the iPad and Mac lines
• Amazon makes 90% from its “Product” and “Media” categories, and 9% from AWS
• Microsoft is diverse: Office (28%), servers (22%), Xbox (11%), Windows (9%), ads (7%), Surface (5%), and other (18%)

The doughnuts are simple and easy to read with match brand colors and a minimal number of slices. I always prefer that pie charts and doughtnut charts consistently start at the top, but these are aligned with the callouts to the right. I also prefer the slices to be sequenced in descending order.

One potential issue is that the doughtnut charts are all the same diameter, which can visually imply that all of these companies are similar in size. I know the market capitalization, revenue and earning are shown in bars to the left, but they're much smaller. I think it would work better if the doughnut charts were actually sized to match each company's revenue number.
