Three laws of visual communication
for the quantitative scientist. Effective visual communication follows three laws: 1.) Have a clear purpose; 2.) Show the data clearly; and 3.) Make the message obvious. These three laws correspond to the three main ingredients of any quantitative work: purpose, data, and message. Getting these right leads to success; failing in any of them leads to overall failure.
