This gives a list of the first 8 digits of π in base 10, followed by the number of digits to the left of the decimal point:

Use First if you want just the list of digits:

This writes the digit 5 in a 50-point font (a “point” is a printer’s measure equal to 1/72 inch):

This writes the digits from 1 to 5 in font sizes proportional to their values:

A more efficient way to write the same thing uses a pure function. This is a pure function that adds 3 to a number:

Use it to add 3 to 5:

Use the pure function to add 3 to every element of a list:

You can apply styles with pure functions. This makes the font size of each digit proportional to its value. It’s the same result that you saw before:

Use Row to turn the list into a row of digits without braces or commas:

Do the same thing with the first 100 digits of π :

Type \[FilledCircle ] to get a disk character:

Make a large disk:

Make disks whose sizes are proportional to the digits of π :

RandomColor gives a different color each time it’s run. Try running it several times:

Make a 100-point disk with a random color:

Make randomly colored disks sized according to the digits of π :

Put a Pane around each disk to make the disks line up. A Pane is an invisible container that takes on the height of the row and the width of its contents. The disks are centered vertically within the panes, which makes them align on their centers:

Deploy a form that makes a digit necklace with the starting digit and number of digits you specify:
