"I say there is no darkness but ignorance." William Shakespeare. Any intelligence we may have come upon is only by chance, our lives are ruled by chance, so we cannot judge harshly those lives that have not had the good chance to see beyond the ignorance that surrounds much of life.
Timelines are a wonderful way to display information so people can better understand a chain of events in sequence. I thought this timeline of William Shakespeare was interesting because it showed the progression of his life and his work within the same information graphic. http://timelines.com/
