Whoa - he didn't put a time scale or units on his graph are we looking at one month, one year, or 50 years?
His graph definitely looks more attractive but I would add that it's very important to put scales and units on your graph. And don't trick people by playing with the units. Make sure that they are meaningful.
1) You're trying to deceive your audience. It's one of the many ways covered in the classic, "How to lie with statistics"
2) You're presenting secret data. You're allowed to show the trends, but not any of the actual units.
Also, I thought the title on this graph was misleading. it said "Rapid Growth", and certainly, it was going up, but rapid compared to what? You always want to be asking yourself, "compared to what?" when you're looking at visualizations.

This is not one of those rules you want to break.
