An infographic should communicate an insight or story from the data to the audience. An insight should be something new and interesting your audience doesn’t commonly know.
Wireframe your story before you start any design work
Layout the information flow that will effectively educate your audience with your new insight from the data. Consider using a 3-part story format: an Introduction with background information, the Key Message that displays your data insight and a Conclusion or Call-To-Action.
Experiment with design ideas by creating rough concepts that visualize your data in a handful of different ways
Your want your visuals to be easy to understand and relevant to the data but you don’t want your design to look like a template or a boring chart. One set of data can be visualized in many different ways, so try to find a new way to show the insight.
Choose one design direction or combine a few different ideas from your concepts. Design a complete first draft in that style, and include all of the relevant visualizations, illustrations and text in the layout you defined with the wireframe. Then iterate a handful of times by reviewing the design with you client or co-workers to simplify the design. You want a clear concise story with minimal text and clutter
The final step is to finalize your design with the appropriate Copyright or Creative Commons license, and export the final design to a few different file formats as necessary.
Use a JPG image file to publish online and a PDF file to share the infographic through email. You may even want a few different JPG file sizes to share in social media and blog posts.
