This picture is of a radar plot with eight dots connected with lines to form a geometric shape. It is an octagon with two sides on the left side poking inwards.
This Radar Plot 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 5,700 icons, all in the same style and quality.
