What Goes Up, Must Come Down
I love a drawing that tells a story. Here’s an illustration that does just that; it’s a diagram showing the flight path of James Glaisher’s balloon on 18 August 1862, which travelled between Wolverhampton and Solihull, just outside Birmingham in England. It’s essentially a graph that plots altitude over time, with some embellishments added for effect. The story being told is in the graph’s line, which ascends and descends just as the balloon did during its flight.
