+
+##  📣 Description
+
+This is a `functional` version of [cutecharts.java](https://github.com/cutecharts/cutecharts.java) which I want try to write `Java` on `non-Java`. :dog:
+
+Definitely, It is more fun to make something has more possibilities.
+
+
+##  🔖 Documentation
+
+> All the configurations detail you can find on there [chart.xkcd](https://timqian.com/chart.xkcd/).
