An infographic isn't just a bunch of data on one piece of paper. In every set of data, there's a story. Infographics use data to tell that story in a compelling, visual manner. Before you begin designing your infographic, think of the story you are trying to tell. Ask yourself:
Before diving into your design, create an infographic outline. In your outline, include your headers, data, and any design details you don't want to forget. Be aware of visual elements, like arrows, lines, or color schemes, that can be used to lead the viewer's eye through your narrative.
Come up with a title that is catchy and descriptive. Readers should get a sense of what the information will be, to engage them and make them want to read further.
If your goal is to inform your viewer of a statistic, a donut chart, pictograph or even just the number is appropriate. To compare data, use a bar, bubble, or pie chart. You might also use a treemap or a word cloud. To show change over time, use a line, area or map chart or a timeline. To show relationships between datasets, use a scatter plot. Finally, to organize information, use a list, flow chart, venn diagram, concept map or put the data in a simple table. This graphic shows examples of the types of charts mentioned above.
Draw a storyboard by hand (even if you have to use stick figures and little blobs that you label so others can tell what they are). This allows you to determine what sorts of images, icons and text you need to include and what layout looks most pleasing. Once you have a hand drawn storyboard, use a tool like Adobe Color (https://color.adobe.com/create) to choose a color palette and plan what colors to use in your design. Make sure your palette has 3-5 contrasting colors - base color(s) and a highlight color, at least. Use colored pencils or even crayons to color in your storyboard to see if you like your color palette. (Pro Tip: make photocopies of your story board before coloring it in case you want to try multiple color palettes).
Symmetrical balance is when each aspect of the infographic has equal weight. This layout is effective in a comparison infographic or an infographic that shows linear progression. Asymmetrical balance gives more weight to certain areas of the infographic. The more weighted areas have more visual importance. A good way to create your symmetrical or asymmetrical balance is by dividing your infographic using blocks of color. You can use light/dark values of the same color (ex. light and dark blue) or you can use contrasting colors. When using contrasting colors, brighter colors, like red, orange or yellow, should carry the most weight and contain the most important information.
If you start out using colored-in icons, don't throw in a random line-art icon or picture. If you start out using blue line-art icons, don't throw in a random red icon just because that's the only free version you could find. (Use the red icon if that data should stand out from all the rest).
Negative space is the blank space surrounding objects in a design. If your infographic design is too crowded, it can overwhelm readers and make it difficult to read the information. One element that can visually clutter an infographic is the over-use of photographs. Use photographs sparingly; choose photographs with common color palettes; or make photographs transparent background images to avoid this problem.
Some fonts are academic/business-like/professional. Some are fun. Choose wisely to keep the focus on your message. Also, don't use more than two fonts. Use a decorative font or font colors to call attention to important, headline items. Use plainer fonts for bodies of text. You can read tips for choosing a font here: Selecting Type for Text
All these charts and graphs can be created using Excel or Power Point.
If the information you are trying to convey is important enough to put into an infographic, it is important enough that everyone should be able to access the information. The problem with that is: because infographics are visual material, they are fundamentally not accessible to users with visual or cognitive disabilities. There are ways to make your infographic accessible. A good website to help with that is:
