Seamless interactivity

On the left (or top for mobile devices) is the vector field of the gradients of the following function:

Change to see how it changes the vector field.
Type a = \scalar 1.2 in the editor at bottom left and test it out for different values of a yourself.

Insightful visualizations

Click the teal text to see different ways to visualize a matrix transform:
- shows how it transforms a uniform grid.
  - , see where the point lands and where the point lands.
- shows how it maps points on a circle to points on an ellipse.
anything to illustrate the behavior of certain properties over time.

Autograd enabled

The of total distance from the origin of each point.
- , the gradients also update reactively.

Implement your own figures

You can build your own extension and import it here to visualize and interact with it. This is actually how most of the commands you will encounter here have been implemented.

... and much more.
