This is a very informative graph that shows the market cap of all the top companies. It helps to put the sense of big numbers in context of each other. As of the date of the Facebook IPO, Apple was the world's largest company in terms of market capitalization value. Market capitalization is simply calculated by the price per share multipled by the number of shares outstanding.
Apple is valued at close to $500 billion while Facebook is valued at $104 billion.
Some other recognizable names include Apple, Exxon Mobil, Microsoft, IBM, Berkshire Hathaway, Wal-Mart Stores, Google, General Electric, Chevron, AT&T, Procter & Gamble, Johnson & Johnson, Coca-Cola, Pfizer, Wells Fargo, and more.
Facebook ranks at 23rd on the above list.
The metrics used in the bar chart are in millions, as indicated on the graph. So the way to interpret this graph in terms of numbers is to take that millions and multiply it by the number that you see beside each individual chart.
Since most of the numbers on the bar chart are in the hundreds of thousands - if we add another 6 digits, that would bring is into the hundreds of billions range.
So a number like 100,000 shown on the chart, would actually be 100,000,000,000 or $100 billion. So get this metric correct. You don't want to mix up hundreds of thousands with millions, billions or hundreds of billions.
You'll see these kinds of unit and metrics manipulation quite often on the GMAT graphics interpretation questions. It's generally one of the best ways to make a seemingly easy graphics interpretation question more difficult.
