## Use it with sparkline
-Well, this is not a feature but rather a documentation of how to use the `sparkline` package together with this package. The easiest way is sort of a hack. You can call `sparkline::sparkline(0)` somewhere on your document where no one would mind so its dependencies could be loaded without any hurdles. Then you use `sparkline::spk_chr()` to generate the text. Here is another example: [Chinese names in US babynames](https://cranky-chandrasekhar-cfefcd.netlify.app/)
