Author Stephanie Evergreen advocates for "Building a Culture of Effective Data Visualization". In her closing chapter she says:
"Whether data visualization and good design make a difference in communicating data almost shouldn't ever be a question. It has a sort of validity that hits you right between the eyeballs. Once you see what good graphic design can do to data, it can be difficult to go back to the traditional way of reporting. Beyond how good it looks, we have strong evidence that elements like color and font impact comprehension, that the presence of graphs and photographs increases credibility and persuasiveness, and that certain graph types will be better than others at telling an accurate data story."
Scanning Stephanie's book is definitely worth the effort. Remember, the object of this book is to show you "How to select from the specific range of charts available that are most suited to the type of data being presented."
