Hello,
Thanks for the comment. The "mm" signifies millions which is the amount the timeline is representing, $6 million from 125,000 donors globally. If we were to replace it with one "m", that would signify only $6 thousand.

"M" before the abbreviation of a unit means 1,000, but on its own it is far more commonly used to mean 1,000,000. "m" never means 1,000 - it means 1/1,000 when used with the abbreviation of a unit, but on its own it usually means 1,000,000 too.
I beg to differ, Thomas. It may be an Americanism (I would have to find a source for that), but "M" is generally understood to refer to thousands in currency. It comes directly from the Latin "Mille".
