Many experienced analysts often create graphs that are difficult to read, don’t convey the correct information, or accidentally leave the audience with incorrect understanding of the data presented. This is risky and can lead to bad decisions. Further, it is avoidable. Information does not speak for itself. Information relies on us to give it a clear voice and tell the story.
The reality is that very few people have been trained on how to properly present data in tables and charts the most appropriate way. The good news is that these design skills are quick to learn in the classroom.
