Icon
An icon is a powerful and recognizable expression of a brand. Unlike logos, icons differ according to their function. Think of Google. Each of their services – like Gmail or Gdocs — have a recognizable icon. These symbols need to be consistent with the brand’s identity.
Overall, an excellent icon needs to increase the brand’s recognition, while also being intuitive for the target audience.
Infographic
In short, an infographic is a visual communication tool. Infographics are generally used to tell a story through visual elements and minimal text. It makes complex data easier to grasp and entertaining.
Invoice
An invoice is a bill, evidence of the sale that occurred. Usually, its header contains the brand logo and contact details.
