This is a list of miscellaneous resources I’ve come across dealing with data visualization in several forms.
These are mostly utility libraries and viewers that I had scattered all over the place and that are best concentrated on a single page for reference.
The Graphs and Graphing and Visualization pages will be subsumed by this one in the fullness of time.
Ratings are entirely subjective based on my interest.
