<script>
  console.log(d3plus);
</script>

Live examples can be found on d3plus.org, which includes a collection of example visualizations using d3plus-react. These examples are powered by the d3plus-storybook repo, and PRs are always welcome. 🍻

• format - An extension to d3's format function that adds more string formatting types and localizations.

The new specifier strings added by d3plus-format are:

• .3~a - abbreviated decimal notation with a numeric suffix (ie. "k", "M", "B", etc). This is an alias of the formatAbbreviate function.

• formatAbbreviate - Formats a number to an appropriate number of decimal places and rounding, adding suffixes if applicable (ie. 1200000 to "1.2M").
• formatDate - A default set of date formatters, which takes into account both the interval in between in each data point but also the start/end data points.
• formatDefaultLocale - An extension to d3's formatDefaultLocale function that allows setting the locale globally for formatters.

• formatLocale - A set of default locale formatters used when assigning suffixes and currency in numbers.
