An infographic is an image that combines information, storytelling, and perceptions to communicate a message effectively. It uses various design elements like lines, shapes, colors, and their arrangement to catch viewers' attention regardless of their background. Creating a balanced composition with formal or informal symmetry using these elements with proportion and rhythm helps ensure the infographic's message is understood. Common file formats for infographics include JPEG, TIFF, GIF, and PNG, each with their own compression techniques and capabilities.
