Default format function - converts value to string.
Strings pass through unchanged. A number of DEFAULT_GROUPING_THRESHOLD
or more has its digits grouped in threes with commas (12,345), the default
for every axis that declares no format; a declared format replaces it.
A fractional number is rounded as defaultLabelFormat describes.
The commas are always , with . for decimals, whatever the reader's
language, matching the decimal point this format has always used; an author
whose readers expect another convention declares a number format with a
locale.
