xtal-treant is a dependency free web component wrapper around the great Treant library.
The web component requires a property, "config" to be set:
Because the library is designed to create different tree charts, based on a passed on css file, this raises a bit of a cunnundrum for a reusable web component. You can pass in the css file in the config setting. This will dynamically pass the css content into the shadow DOM. This currently has some issues in Chrome.
So the better alternative is to define a preload link in document.head:
Note the use of "treant" and "css" in the class, and the data-postfix value.
This will cause xtal-treant to dynamically create a new web component with name xtal-treant-basic, with the contents of the css file stamped into the template.
