  Visualization, as a vibrant field for researchers, practitioners, and higher
educational institutions, is growing and evolving very rapidly. Tremendous
progress has been made since 1987, the year often cited as the beginning of
data visualization as a distinct field. As such, the number of visualization
resources and the demand for those resources are increasing at a very fast
pace. We present a collection of open visualization resources for all those
with an interest in interactive data visualization and visual analytics.
Because the number of resources is so large, we focus on collections of
resources, of which there are already very many ranging from literature
collections to collections of practitioner resources. We develop a novel
classification of visualization resource collections based on the resource
type, e.g. literature-based, web-based, etc. The result is a helpful overview
and details-on-demand of many useful resources. The collection offers a
valuable jump-start for those seeking out data visualization resources from all
backgrounds spanning from beginners such as students to teachers,
practitioners, and researchers wishing to create their own advanced or novel
visual designs.
