Graphing software is used by students and professionals to plot both data and equations, including 2D and 3D images.

Review Results
This review is in work. Until the review is complete, I suggest the following application for your graphing needs:

• DPGraph
  This program has been around for years and has been licensed to over 1,000,000 users. It's one of the most impressive, fastest graphing tools I've ever seen.

  DPGraph sells for $10, but major price reductions are available for site/group licenses.

Graphing Software Features
These are the minimum features that I expect from graphing software. Each of the candidate programs will be ranked against how well they implement these features. As the review continues, the list of features may change.

1. Ease of use
2. Surfaces (color/font/texture)
3. Plot from data or equations
4. 2D/3D images
5. Rotation
6. Animation
7. Visual options (colors, background, images)
8. Equation entering aides

Candidate Programs
These are the programs included in this review.
