This is a data visualization I had been meaning to do for almost a decade. It's very close to my heart as I had a small business making subatomic particle toys. Because there is such a vast difference between the largest and smallest subatomic particles, this graphic was one of the most challenging I've ever done. Over the course of two months, it went through many iterations which I documented here in my DataViz blog. To make the graphic more relatable and accessible for the general public, I included the top five mysteries of particle physics and how studying particles may help solve them. Special thanks to James Gilles of CERN who consulted and gave valuable criticism and feedback as this graphic was evolving.
