Pi Digits Bar Chart
Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
Each bar shows how many times a given digit appears in the decimal expansion of to the given number of digits. Notice that zero does not appear until the thirty-third digit, but after 10,000 digits, 0 appears approximately as often as the others. It is currently unknown whether the distribution of digits becomes more uniform as the number of digits approaches infinity.
