The image author said he used Microsoft PowerPoint2010 SmartArt to draw it.
I tried but I can't even draw rectangles using SmartArt.
Can SmartArt really draw this? If so, please explain it to me.
Or is there any tool else more nicer than smartart?
I'd really like to draw an image like this.
I don't mind any answer if it gives me an ability to draw this.
