Idea of Bar Chart Icon
This icon looks just like a bar chart, but uses only three rectangles of various heights. The rectangles are ordered from left to right with the middle sized one on the left, the shorter one in the middle, and the taller one on the right.
This Bar Chart icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 6,100 icons, all in the same style and quality.
