Idea of Futures Icon
It's an image of four tall, vertical rectangles of different height situated next to each other. The bases of the rectangles are at the same height, with a line extending across the base of all the rectangles. Two of the rectangles are filled in with dots. It looks like a bar graph or side-by-side buildings.
