Which item type would you assign to a chart?

I mean, the linked one below, for example:

If I was interested mostly in the graphics and design, I'd use Artwork, or maybe just Document.

Otherwise I might use Dataset and refer to the original data on Github.

Thanks! I finally used Document. The other option I had thought was Presentation.
