Call me a nerd but I find this chart created by Data Pointed fascinating. It captures the evolution of the number of crayons produced by Crayola over the last 107 years. At the heart of the chart is the original eight created in 1903 while the outer rim showcases how those colour categories grew into 133 crayon colours available today. The only thing missing is the intoxicating smell of opening a fresh box of crayons!
