Observatory
Observatory is a free .NET library that lets you create beautiful, interactive plots.
// C#
using ObservatoryLib;
...
Plot3d plot = new Plot3d();
plot.Drawing.AddPoints(...);
plot.Display();
Observatory has tools for visualizing numerical data in a variety of ways: scatter plots, histograms, heat maps, images, mathematical functions, and more.
I've done my best to make it super easy to launch a basic plot, but there are also more advanced features that give you a great deal of flexibility to customize your plotting environments.
